Abstract: An electrophotographic system is constituted by an electrophotographic photosensitive member, charging means for charging the photosensitive member to a potential, and exposure means 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 varying depending on an electric field intensity induced by the charged potential. The electrophotographic system further includes control means 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.

Abstract: An electrophotographic photosensitive member is constituted by an electroconductive support, and an intermediate layer and a photosensitive layer disposed in this order on the support. The intermediate layer comprises a reaction product of a mixture including a polyol compound [A] and a polyisocyanate compound[B] satisfying at least one of the following conditions (i) and (ii): (i) the polyol compound [A] is a high-molecular weight polyol compound, and (ii) the polyisocyanate compound is a polyoxyalkylene segment-containing polyisocyanate compound. The photosensitive member shows stable electrophotographic performances over wide environmental conditions from low temperature - low humidity to high temperature - high humidity due to the intermediate layer.
