Electrophotographic photoreceptor, process cartridge, and image forming apparatus

Abstract

An electrophotographic photoreceptor includes a conductive support, a charge generation layer disposed on the conductive support, and a charge transport layer disposed on the charge generation layer. The charge generation layer includes a charge generating material and a vinyl copolymer. The vinyl copolymer includes a structural unit including a chlorine atom, a structural unit including an acyloxy group, and a structural unit including two or more carboxyl groups. The proportion of the structural unit including an acyloxy group to all of the structural units is 13.4 mol % or more and 20.0 mol % or less. The charge transport layer includes a charge transporting material and a binder resin.
