本発明は有機光導電体層上に表面保護層を設け
た電子写真用感光体の製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a method for manufacturing an electrophotographic photoreceptor in which a surface protective layer is provided on an organic photoconductor layer.
従来技術

けることになる。Prior Art In the electrophotographic method conventionally known as the Carlson method, a large number of copies are made by repeating the processes of charging, exposing, developing, transferring, and cleaning. Therefore, the surface of the electrophotographic photoreceptor is constantly subjected to mechanical, electrical, and chemical stress.
このため、感光体の損傷を防ぎ、寿命を高める
ため表面の機械的強度改善のために保護層を設け
ることが行われている。 For this reason, in order to prevent damage to the photoreceptor and extend its life, a protective layer is provided to improve the mechanical strength of the surface.
カールソン法では保護層として、電気抵抗を
109〜1014Ω・cmにした低抵抗保護層が用いられ

層が形成されるが、熱硬化性樹脂を有機光導電体
層上に塗布したのでは保護層表面が白濁化すると
いう欠点がある。 The Carlson method uses electrical resistance as a protective layer.
A low resistance protective layer with a resistance of 10 9 to 10 14 Ω·cm is used. This protective layer is formed by applying a coating liquid containing a resistance adjuster to a thermoplastic resin or thermosetting resin as a resin component. When a thermosetting resin is used as the resin component, a protective layer with high surface hardness is formed, but when a thermosetting resin is applied on an organic photoconductor layer, the surface of the protective layer becomes cloudy. .

ングするといつた欠点がある。 If clouding occurs on the surface of the protective layer, undesirable phenomena such as decreased sensitivity, decreased resolution, and fog on copies occur when used as an electrophotographic photoreceptor. Furthermore, since a curing process is required at high temperatures for a long period of time, work efficiency may deteriorate, the organic photosensitive material in the photosensitive layer may decompose and the photosensitive characteristics may be impaired, or the sheet-like photoreceptor may block. There are some drawbacks.

基づいて本発明を完成させる至つた。Composition of the Invention In view of the above-mentioned object, the present inventors have made extensive studies and found that when applying a surface protective layer, by incorporating an organic tin compound into the coating solution, it is possible to eliminate the need for a special curing treatment process and to apply a surface protective layer using a normal coating process. Based on this finding, the present invention was completed based on the discovery that a surface protective layer of sufficient hardness without clouding of the surface could be provided by drying alone.
