SF431 (trade name) and the like, but are not limited thereto.

The liquid application unit 34 includes a liquid container 39 filled with a predetermined amount of the processing liquid 33,
A liquid transport roller 40 that transports the originals 2 and 20 into the processing liquid 33 in the liquid container 39 while contacting the upper surface with the upper surface; It is composed of a pair of squeezing rollers 42, a squeezing bar 43, etc., which is arranged to bite into the lower squeezing roller 42. In the liquid application unit 34, the fed various originals 2 and 20 are guided into the processing liquid 33 in the liquid container 39 by the submerged conveying rollers 40 and the submerged guide plate 41, and are immersed in the processing liquid 33. After that, the excess processing liquid 33 is removed by the squeezing roller 42 and the toner peeling unit 3
6 is transported.

The toner peeling unit has a built-in heating lamp 44 which functions as a softening means for the toner, and a pair of the peeling rollers 35 arranged in a press-contact state, and the surface of the peel roller 35 near the press-contact portion on the transfer paper discharge side. And a cleaning device 46 that cleans the surface of the peeling roller 35. The surface of the peeling roller 35 is formed of a material having an adhesive force greater than the adhesive force between the various originals 2 and 20 and the toner, at least with respect to the softened toner. Specifically, a toner component resin that is the same as or similar to the toner described above, a component resin of an adhesive, or the like can be used, and a metal material such as an aluminum-based or copper-based nickel-based material can also be used. However, the present invention is not limited to this. These resins may be water-soluble or water-insoluble.

Here, examples of the toner component resin include polystyrene resin, acrylic resin, methacrylic resin, styrene-butylacrylic copolymer, styrene-butadiene copolymer, polyester resin, epoxy resin and the like. It is not limited.

The component resins of the adhesive include protein adhesives such as glue, gelatin, albumin, and casein, and carbohydrate adhesives such as starch, cellulose, and complex polysaccharides (eg, gum arabic and tragacanth). Agent, vinyl acetate polymer and copolymer, acrylic,

ET) and the like, but are not limited thereto.

When these resins are used, it is desirable to form a multilayer structure of at least two layers of a support and a surface layer from the viewpoint of prevention of elongation due to tension and heat, durability and the like. As described above, when a roller-shaped peeling member is used, it is desirable to form a peeling member by forming a surface layer made of such a resin on a base roller as a support. Examples of the support for supporting such a resin include, but are not limited to, a rubber roller, a sheet, a cellophane tape, a kraft paper adhesive tape, a polyvinyl chloride tape, an acetone tape, a tape such as a filament reinforcing tape, and the like.

Further, the heating lamps 44 of the upper and lower peeling rollers 35 heat and soften the toner adhered to the various originals 2 and 20 by being in close contact with the front and back of the various originals 2 and 20. This is to make it easy to peel off from the fibers of the various originals 2 and 20. This heating is desirably performed to such an extent that the toner on the various originals 2 and 20 does not melt at the pressure contact portion. When the toner melts, various originals 2,
This is because it is difficult to transfer the toner on the transfer roller 20 to the separation roller 35 without separating the toner into the paper side and the separation roller 35 side. Further, if the heating is performed excessively, the various originals 2 and 20 are excessively dried while passing through the pressure contact portions of the pair of peeling rollers 35, and the fixing force of the toner to the various originals 2 and 20 causes the various originals 2 and 20 to be wet. This may be stronger than in the case, and may adhere to the peeling roller 35 via the various originals 2 and 20 and cannot be separated by the separation claw 45. Therefore, it is desirable to heat the various originals 2 and 20 after passing through the heating unit to such an extent that some moisture remains and toner re-adhesion can be prevented.

The cleaning device 46 includes a cleaning roller 4 for erasing toner on the surface of the peeling roller 35.
7, a scraper blade 48 for scraping off toner on the cleaning roller 47, and a scraper blade 4
And a toner container 49 for accommodating the toner scraped off in step 8. The peeling roller 35
Instead of using a belt having the same surface characteristics, a cleaning roller 47 of the cleaning device 46 may be used.
Instead, a cleaning blade, a scraper, or the like directly contacting the surface of the peeling roller 35 may be used.

The drying unit 38 includes various originals 2, 20
And a drying roller 37 made of, for example, aluminum or the like and having a built-in heating lamp 50.
And a pressing roller 51 pressed against the drying roller 37 from below. This pressing roller 5
Reference numeral 1 denotes a surface layer made of a liquid-supplying member, and a diaphragm blade 52 for squeezing the liquid on the surface layer comes into contact with the surface layer. Instead of or in addition to the pair of rollers 37 and 51, a belt-shaped member, a hot-air fan, an infrared lamp, or the like may be used.

Although not particularly shown, the toner erasing section 9 of the present embodiment includes means for detecting the remaining amount of liquid in the liquid container 39, means for automatically replenishing the liquid container 39, and detection of jams of the various originals 2 and 20. Means, lighting control means for each heating lamp, toner container 4
Nine full detection means and the like (both not shown) are appropriately provided.

In such a configuration, the facsimile apparatus 1 sequentially conveys the transmission original 2 placed on the original platen 3, converts the print image into image data by the scanner 6, and converts this image data from the image by the CODEC 17. The data can be converted into a code and transmitted from the communication control unit 18 to another facsimile apparatus (not shown) via the communication line 19. Further, the facsimile apparatus 1 reproduces image data received by the communication control unit 18 from another facsimile apparatus via the communication line 19 from a code to an image by the CODEC 17 and temporarily stores the image data in the reception image memory 31. The image recording unit 28 can also print out the received paper 23, 25 fed from one of the first and second paper cassettes 24, 26.

[0055] Then, the facsimile machine 1, the image data of the transmission original 2 placed on the original manuscript platform 3 scanner 6
In the case where the document is scanned and transmitted to the outside, the transmitted document 2 having passed through the position of the scanner 6 is guided to the second document conveying path 10 by the selector mechanism 11, and the toner is erased by the toner erasing unit 9, The transmission original 2 from which the toner has been erased can be supplied to the second paper cassette 26 as the reception paper 25.

When the transmission original 2 is reproduced on the receiving paper 25 as described above, the toner erasing section 9 applies the processing liquid 3 to the toner image surface of the fed transmission original 2 by the liquid applying unit 34.
The toner fixed to the transmission original 2 is softened by heating the peeling roller 35 by the toner peeling unit 36 so that the toner
The transmission original 2 having the toner adhered to the surface and from which the toner has been removed is dried by the drying unit 38 and discharged.

At this time, in the toner erasing section 9, the processing liquid 33 is supplied to the transmission original 2 to which the toner has adhered, and the toner is removed in a state where the processing liquid 33 permeates the interface between the transmission original 2 and the toner. The toner can be erased without damaging the paper fibers. Further, the paper surface is brought into contact with the peeling roller 35 while being wet with the processing liquid 33, and
Since the paper is heated to such an extent that the paper can be kept moist even when it is separated from the paper, even when the surface of the peeling roller 35 is made of a material having toner adhesiveness, the paper itself adheres to the surface of the peeling roller 35 and is separated. Can prevent defects from occurring,
Further, it is possible to prevent the toner from re-transferring due to the separated paper portion coming into contact with the peeling roller 35 again.

As described above, in the facsimile apparatus 1, if the transmission original 2 does not need to be stored after the image transmission is completed, the transmission original 2 is reproduced on a blank reception sheet 25 to print out the reception image. It can be used for
It is possible to prevent the transmission original 2 from being discarded and wasteful consumption of resources, and reduce the shortage of the reception paper 25. Here, it has been exemplified that supplied to the second paper feed cassette 26 by playing the received paper 25 to transmit a document 2 from the read image by the scanner 6, the image reading of the transmit document 2 by the scanner 6 It is also feasible to reproduce the received paper 25 and supply it to the second paper feed cassette 26 without executing it.
