Abstract

PURPOSE: To maintain always good chargeability and photosensitivity even in the case of continuous copying operation by containing chlorinated rubber as part of the binder of a charge-transfer layer in the electrophotographic photoreceptor formed by laminating a charge-generating layer and charge-transfer layer on a conductive substrate.
CONSTITUTION: In the electrophotographic photoreceptor formed by subsequently laminating a charge-generating layer such as of Se or phthalocyanine and a charge- transfer layer composed of polyvinyl carbazole, pyrazolone derivative, etc. and a binder (polycarbonate, polyester, etc.) on a conductive substrate such as metal plate like Al plate or plastic sheet comprising depositing metal or conductive metal oxide on the surface; chlorinated rubber is compounded at about 1W50wt% (preferably 5W30wt%) and is used as part of the binder for the abovementioned charge-transfer layer. It is desirable that the abovementioned chlorinated rubber be of around 65% in chlorine content.
