ELECTROPHOTOGRAPHIC PHOTOSENSITIVE MEMBER, PROCESS CARTRIDGE AND ELECTROPHOTOGRAPHIC APPARATUS |
摘要 |
<p>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.</p> |
