つた。 Conventionally, the general method for visualizing an electrostatic image formed on an electrophotographic photoreceptor or electrostatic recording material is to transfer the image developed with toner onto paper, and then transfer the toner to paper by heating or applying pressure. A method has been proposed to establish this. This method has the advantage of allowing recorded images to be obtained on low-cost plain paper, but on the other hand, the toner, which is the developer, is a consumable item and needs to be replenished, so maintenance is extremely complicated. .

応じて通常の手段により静電像を形成する。 The principle of the recording method according to the present invention will be explained in detail below based on the drawings. First, as shown in FIG. 1, an electrostatic image is formed on a recording medium 1 capable of carrying an electrostatic image, such as an electrophotographic photoreceptor or an electrostatic recording medium, by conventional means depending on the respective recording medium.

Further, the shape of the fine particles is preferably spherical in terms of excellent filling properties. Furthermore, in order to obtain clear images with less fog, the particle size is preferably from several microns to 30 microns.

Next, the particle image obtained in FIG. 2 is transferred by a conventional means of electrostatic transfer by bringing the particle image into close contact with the recording paper 3 using, for example, a corona charger 4.

Then, only the part of the pressure-sensitive recording paper where the particle image is located is strongly pressurized, the microcapsules are destroyed, the leuco dye and the color developer react, and a colored image is obtained. Next, although not shown, when the fine particles 3 on the pressure-sensitive recording paper are removed using, for example, a brush, a visible image corresponding to the electrostatic image is obtained on the pressure-sensitive recording paper. The removed fine particles are again used for the development shown in FIG.

目も10000回目も同じであつた。Example 1 An ordinary selenium photoreceptor obtained by vapor-depositing selenium on an aluminum plate was positively charged and imagewise exposed to obtain an electrostatic latent image. Next, when spherical glass beads with a particle size of 5 to 20 microns were scattered on the photoreceptor and an air jet was applied, a state was obtained in which the glass beads were electrostatically attached only to the area where the electrostatic latent image was located. Next, a commercially available pressure-sensitive recording paper DiaSelf (manufactured by Mitsubishi Paper Mills Co., Ltd.) was placed in close contact with the particle image, which had been irradiated with light onto the photoreceptor to weaken the electrostatic attraction between the photoreceptor and the glass beads. Glass beads were electrostatically transferred onto pressure-sensitive recording paper using a corona charger that applied a voltage of . Next, the pressure-sensitive recording paper supporting the glass beads was pressurized with a pressure of 80 kg/cm 2 using a flat plate pressurizer, and the glass beads were wiped off with a brush. The image was recorded.
10,000 wiped glass beads using the method described above.
When used repeatedly, the image quality obtained was the same both the first time and the 10,000th time.

A particle image consisting of melamine particles corresponding to the electrostatic image was obtained. Next, in the same manner as in Example 1 (however, the applied voltage of the corona charger was set to -6 KV), the particle image was electrostatically transferred onto a pressure-sensitive recording paper, which was then pressurized with a flat plate processing machine, and then the particles were transferred with a brush.
