Process cartridge and electrophotographic apparatus

摘要

An electrophotographic photosensitive member is constituted by a support and a photosensitive layer disposed on the support. The electrophotographic photosensitive member has a surface layer comprising a polyester resin having a recurring unit represented by the following formula (1): <CHEM> wherein A1 represents a substituted or unsubstituted divalent aliphatic hydrocarbon group. The resultant surface layer is effective in improving an abrasive resistance of the photosensitive member.
