Problems solved by technology

[0006] However, in the case where toluene or xylene is used as a solvent for a coating liquid for a surface layer containing a resin having a siloxane structure to reduce the contact stress of the surface layer, compared with the case of using monochlorobenzene, it is not sufficient. To obtain the effect of reducing the initial coefficient of friction, it is necessary to reduce the initial coefficient of friction

Embodiment 1

[0159] An aluminum cylinder having a diameter of 30 mm and a length of 260.5 mm was used as a support (conductive support).

[0160] Then, using 12 parts of SnO 2 Coated barium sulfate (conductive particles), 3 parts of titanium oxide (pigment for resistance adjustment), 6 parts of phenolic resin (binder resin), 0.001 part of silicone oil (leveling agent), and 4 parts of methanol and 16 parts of methoxy A mixed solvent of propanol was used to prepare a coating solution for a conductive layer.

[0161] The coating liquid for a conductive layer was applied on the support by dip coating, and cured (thermally cured) at 140° C. for 30 minutes, thereby forming a conductive layer having a thickness of 25 μm.

[0162] Then, 3 parts of N-methoxymethylated nylon and 3 parts of copolymerized nylon were dissolved in a mixed solvent of 65 parts of methanol and 30 parts of n-butanol, thereby preparing a coating liquid for an intermediate layer.

[0163] The coating liquid for an intermedi...

Embodiment 2 and 3

[0169] Electrophotographic photosensitive members were each produced in the same manner as in Example 1 except that the drying temperature at the time of charge transport layer formation in Example 1 was changed to 115° C. or 135° C.

Embodiment 4 and 5

[0171] Electrophotographic photosensitive members were each produced in the same manner as in Example 1 except that the thickness of the charge transport layer in Example 1 was changed to 10 μm or 30 μm.

Abstract

Provided is a method of producing an electrophotographic photosensitive member including a support and a surface layer formed on the support, the method including the steps of forming a coat of a surface-layer coating solution, and drying the coat to form the surface layer, in which the surface-layer coating solution includes resin [alpha], resin [beta], solvent [gamma], and compound [delta].

Description

technical field [0001] The present invention relates to a method of manufacturing an electrophotographic photosensitive member, a process cartridge, and an electrophotographic apparatus. Background technique [0002] An electrophotographic photosensitive member containing an organic photoconductive substance (charge generating substance) is often used as an electrophotographic photosensitive member mounted on an electrophotographic apparatus. In electrophotographic processing, in order to suppress the occurrence of phenomena such as squeaking of the cleaning blade or lifting of the cleaning blade, a cleaning step of removing residual toner from transfer with the cleaning blade is required to reduce the contact between the cleaning blade and the cleaning blade. Contact stress (coefficient of friction) between electrophotographic photosensitive members. [0003] It has been proposed to introduce a siloxane-modified resin having a siloxane structure in the molecular chain to t...
