More Information
Summary:An electrophotographic photoreceptor abuts against a charging member and/or a developer carrying member with an abutting member therebetween, has a first portion and a second portion abutting against the abutting member along the longitudinal direction of the photoreceptor, and includes a support, a charge generating layer containing a charge generation material, and a surface layer in this order. The first portion includes an undercoat layer containing a polymer of a composition containing an electron transport material and a crosslinking agent and being contiguous with the surface of the charge generating layer facing the support. The second portion includes (i) an intermediate layer being disposed between and being contiguous with the support and the charge generating layer and/or (ii) an intermediate layer being disposed between and being contiguous with the charge generating layer and the surface layer, wherein the intermediate layers each have a Martens hardness of 500 N/mm2 or less.
