Problems solved by technology

In order to reduce the weight of the support body, it can be easily realized if its thickness (wall thickness) is reduced. heat of vaporization and easily cools below the dew point, thus more prone to whitening
[0012] Therefore, in the case of using a thinner support, the density, specific heat, and thickness of the solvent used, the support material, and the thickness of the photoreceptor layer to be formed are controlled as in the above-mentioned prior art 5. Methods whose parameters meet certain conditions cannot prevent whitening

[0089] Next, add a specified amount of an organic solvent having a boiling point of 70° C. or higher shown in Table 1 and Table 2 (the second solvent, the additional solvent in Table 1, and Table 2) into the specified amount of the above-mentioned mixed solution and carry out 10 minutes. Dispersion, thereby making the implementation coating solution of the present invention. In addition, the addition amount of the second solvent (addition solvent) shown in Table 1 and Table 2 refers to the mass percentage of the mass of the second solvent (addition solvent) relative to the first solvent (main solvent), that is:

[0091] A coating solution was applied by dipping to a cylindrical aluminum tube with a cleaned surface of Φ30 mm, L=250 mm, and a thickness (wall thickness) of 0.70 mm so that the thickness of the photosensitive layer after drying would be 35 μm. Coating was performed in an environment of 23 degrees / 60%RH. After the photosensitive layer was formed, the ...

Abstract

The invention relates to a positively-charged single-layer electrophotographic photoreceptor, a method of manufacturing electrophotographic photoreceptor, and an image forming apparatus. The method of manufacturing a positively-charged single-layer electrophotographic photoreceptor including the steps of: producing a photosensitive layer application liquid containing a good solvent with respect to a binding resin and at least one organic solvent having a boiling point of 70 DEG C. or higher; and forming a photosensitive layer by coating a photosensitive layer support base having a wall thickness of 0.7 mm or less, with the photosensitive layer application liquid and then drying the photosensitive layer application liquid. Therefore, even when a thin-walled support base is used, blushing can be prevented.

Description

technical field [0001] The present invention relates to a method for producing a positively charged single-layer type electrophotographic photoreceptor, a positively charged single-layer type electrophotographic photoreceptor produced by the method, and a positively charged single-layer type electrophotographic photoreceptor produced by the method. The photoreceptor is an image forming device that serves as an image carrier. Background technique [0002] Conventionally, an organic photoreceptor (OPC) has been widely adopted as a photoreceptor of an electrophotographic device. The organic photoreceptor is roughly classified into: a single-layer organic photoreceptor formed on a tube base such as aluminum by dispersing a charge generating material (CGM) and a charge transport material (CTM) in a binder. resin; and a laminated organic photoreceptor in which a layer containing CGM and a layer containing CTM are laminated on a tube blank. [0003] Among organic photoreceptors, ...
