Description

  The present invention relates to a collection container that accommodates waste toner and the like, and more particularly, to a collection container for collecting a collected material whose volume can be reduced.

  In an image forming apparatus such as a copying machine, a facsimile machine, a printer, or a complex machine of these, for example, a latent image formed on the surface of a photoreceptor of the image forming apparatus is developed using toner, and the developed toner image is converted into a developed toner image. The toner is transferred onto a transfer sheet as a transfer target, fixed, and then discharged and stored. Untransferred toner remains on the surface of the photoconductor and intermediate transfer body after transfer, but this toner is mixed with paper dust and the performance is degraded.

  FIG. 10 is a block diagram of an example of an image forming apparatus to which the collection container of the present invention is applied. This image forming apparatus 50 is an image carrier that is rotatably held to carry a formed image using an electrophotographic system. 51 drum-shaped photoconductors, charging means 52 for uniformly charging the photoconductor 51, exposure means 53 for exposing the photoconductor 51 charged by the charging means 52 to form a latent image, and exposure The developing unit 54 that visualizes the latent image formed by the unit 53 to form a toner image, and the toner image on the image carrier 51 formed by the developing unit 54 is transferred to the transfer paper of the transfer target (P). A transfer unit 55 for fixing, a fixing unit 56 for fixing the toner image transferred to the transfer paper by the transfer unit 55, a cleaning unit 57 for removing and collecting residual toner after transferred to the transfer paper by the transfer unit 55, Removed by cleaning means 57 Consisting collecting container 0 like for collecting the recovered toner. The photoconductor 51 performs an electrophotographic process along a rotation direction indicated by an arrow F in the drawing, and a charging unit 52 that uniformly charges the photoconductor 51, and the photoconductor 51 that is uniformly charged by the charging unit 52. An exposure unit 53 that forms an electrostatic latent image by exposure, a developing unit 54 that visualizes the electrostatic latent image formed by the exposure unit 53 to form a toner image, a transfer unit 55, and a cleaning unit 57 are arranged. Yes. The exposure means 53 exposes the original (O) placed on the contact glass of the original placement table 60 on the photoconductor 51 based on the image signal read by the reading means 61 to form an electrostatic latent image. . The electrostatic latent image formed on the photosensitive member 51 by exposure is developed into a toner image by the developing unit 54, and the toner image is transferred to the transfer paper fed from the paper feeding device 62. Electrostatic transfer is performed by 55 transfer device 55a. The transfer sheet on which the toner image electrostatically transferred by the transfer unit 55a of the transfer unit 55 is transferred is conveyed to the fixing unit 56 by the transfer belt 55b and fixed, and then discharged to the discharge tray 64 by the discharge roller 63. It is designed to be stored in paper.

  On the other hand, after the toner image is transferred by the transfer unit 55a of the transfer unit 55, the residual toner remaining on the photosensitive member 51 or the transfer belt 55b of the transfer unit 55 remains on the image carrier cleaning unit 57a, Alternatively, it is removed by the transfer belt cleaning means 57b and is prepared for the next image forming step. The collected toner obtained by collecting the residual toner remaining on the photosensitive member 51 or the transfer belt 55b by the image carrier cleaning unit 57a or the transfer belt cleaning unit 57b of the cleaning unit 57 is recovered toner transfer unit 65. The powder air is discharged as a mixture with gaseous air by the powder pump 65a, and the gaseous air is discharged and separated from the filter 65c through the collected toner conveying path 65b made of a bendable elastic tube. From the discharge port 20 a, it is stored in the collection container storage unit 59, separated from the outside and inserted into the collection container set guide 58 that is inserted and attached to prevent the toner from scattering, and is collected and discharged to the collection container 0. After the collection toner is filled, a new collection container 0 that has been reduced in volume and stored compactly Is conversion, the recovery toner filling the collection container within 0 is discarded.

FIG. 11 is a block diagram of the developing means and the collection container mounting portion. The developing means 54 is a two-component developing device and contains a developer composed of a carrier and toner in a developing tank 54a. When the developing unit 54 forms a toner image, the developer toner in the developing tank 54a is consumed, and the toner density corresponding to the toner is reduced. Therefore, in order to suppress a decrease in image density, when the toner density in the developer becomes a predetermined value or less, the toner is supplied from the toner hopper 54b to maintain the toner density in the developer. The toner concentration in the developer is measured by a magnetic permeability sensor 54c attached to the lower part of the developing tank 54a. The toner replenished from the toner hopper 54b via the replenishing roller 54d is stirred and frictionally charged with the carrier by the stirring member 54e in the developing tank 54a. The developer composed of the carrier and the toner is splashed up to the developing roller 54g by the paddle wheel 54f, and is attracted onto the developing roller 54g by the magnet in the developing roller 54g. The developer is transported by the sleeve on the outer periphery of the developing roller 54g, and the excess is scraped off by the developing doctor 54h. The toner in the developer conveyed to the photoreceptor 51 side adheres by a developing bias corresponding to the electrostatic latent image. The toner adhering to the photoconductor 51 by the developing unit 54 is electrostatically transferred to the transfer paper by the transfer unit 55a of the transfer unit 55, but about 10% of the toner is untransferred and is transferred to the photoconductor 51. Remain in. The untransferred toner adhering to the photosensitive member 51 is scraped off from the photosensitive member 51 by the cleaning blade 57a ₁ and the brush roller 57a ₂ of the image carrier cleaning unit 57a of the cleaning unit 57. In the present example, the collected toner is likely to contain foreign matters such as paper dust, and in this example, the toner falls by its own weight from the discharge port 57a ₃ to be collected without being reused, and the collected toner is transferred by the toner guide member 57a _4. The toner is conveyed to the powder pump 65a of the means 65 as recovered toner.

On the other hand, the transfer belt cleaning means 57b of the cleaning means 57 is also provided on the transfer belt 55b of the transfer means 55 so that the toner adheres in contact with the photoreceptor 51 of the non-transfer area or non-image area. Residual toner adhering to the transfer belt 55b of the transfer means 55 is scraped off by the transfer belt cleaning means 57b that is in sliding contact with the transfer belt 55b. Since the scraped toner is likely to contain foreign matters such as paper dust, in this example, the toner falls by its own weight from the discharge port 57b ₁ without being reused, and is collected via the toner guide member 57b _2. The toner is transported as collected toner to the powder pump 65a of the toner transfer means 65. The collected toner collected by the powder pump 65a of the collected toner transfer means 65 is transferred as a gas mixture with gaseous air by the powder pump 65a of the collected toner transfer means 65, and a collected toner transport path 65b made of a foldable elastic tube. A collection container set guide which discharges and separates gaseous air from the filter 65c through the filter 65 and is stored in the collection container storage unit 59 from the discharge port 20a of the recovered product discharge member 20 and is isolated from the outside to prevent toner scattering. It is discharged and collected in a collection container 0 inserted and installed in 58, and is discarded after being filled.
