ELECTROPHOTOGRAPHIC PHOTORECEPTOR, PROCESS CARTRIDGE HAVING THE ELECTROPHOTOGRAPHIC PHOTORECEPTOR, AND IMAGE FORMING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a photoreceptor which permits the control of the sensitivity to exposure light to a desired value without entailing the deterioration of images accompanying the increase of a residual potential and the lower resistance of a photosensitive layer. SOLUTION: The electrophotographic photoreceptor having the photosensitive layer on a substrate is formed by disposing an intermediate layer absorbing the exposure light between the substrate of the electrophotographic photoreceptor and the photosensitive layer. The reason why the sensitivity regulation is possible by this method is based on the mechanism of regulating the sensitivity by regulating the quantity of the reflected light of the exposure light transmitted through the photoreceptor from the substrate without making a contribution to charge generation.
