发明名称 Electrographic Photosensitive Member, Process Cartridge and Electrophotographic Apparatus
摘要 An object of the present invention is to provide an electrophotographic photosensitive member having high durability and hardly causing sensitivity decrease even if short wavelength light, particularly light having a wavelength of 380 to 450 nm is used as exposure light, and a process cartridge and an electrophotographic apparatus having the electrophotographic photosensitive member. The present invention includes an electrophotographic photosensitive member comprising a support and a photosensitive layer which is provided on the support and contains a charge generation material and a charge transport material, characterized in that the surface layer of the electrophotographic photosensitive member contains an aliphatic dicarboxylic acid polyester resin with a weight average molecular weight of 80,000 or more having a specific repeating structural unit, and a process cartridge and an electrophotographic apparatus having the electrophotographic photosensitive member.
