Abstract
An electrophotographic photosensitive member having a surface layer comprising a bisphenol Z-type polycarbonate resin is charged by contact charging. The charged electrophotographic photosensitive member is then subjected to imagewise exposure to form an electrostatic latent image on the photosensitive member, the thus formed electrostatic latent image on the electrophotographic photosensitive member is developed. The electrophotographic photosensitive member shows good resistance to wearing and toner sticking when subjected to electrophotographic image formation including a contact charging process.
