摘要： 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 resin having a specific recurring unit containing polyamide acid structure and/or polyamide acid ester structure. The photosensitive member is effective for providing a process cartridge and an electrophotographic apparatus respectively including the photosensitive member with an excellent photosensitivity and a stable electric potential under any environmental condition.

摘要： 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.

摘要： An electrophotographic system is constituted by an electrophotographic photosensitive member, a charger for charging the photosensitive member to a potential, and an illuminator for illuminating the charged photosensitive member with a light beam to form an electrostatic image thereon. The electrophotographic photosensitive member has a potential-exposure energy characteristic providing an induction energy and a gamma valve varying depending on an electric field intensity induced by the charged potential. The electrophotographic system further includes a controller for controlling the charged potential on the photosensitive member corresponding to resolution and gradation data of an original, so as to optimally reproduce the resolution and gradation, as desired, of the original.
