ABSTRACT:
An electrophotographic photosensitive member is constituted by an electroconductive support, an intermediate layer disposed on the electroconductive support and a photosensitive layer disposed on the intermediate layer. The intermediate layer contains a copolymer having at least two species of a recurring unit having an amide acid structure and/or amide acid ester structure, thus resulting in good film-forming properties. The resultant photosensitive member is effective for providing a process cartridge and an electrophotographic apparatus respectively including the photosensitive member with a stable electric potential under any environmental condition to provide excellent images free from image defects for a long period.
