摘要： The present invention provides an electrophotographic photoreceptor (10) which is capable of suppressing discharge degradation at the time of roller charging and of forming an excellent image with excellent abrasion resistance, in the case of mounting a roller charging system.
The present invention can be achieved by an electrophotographic photoreceptor (10) in which an electric charge generating layer (10c) and an electric charge transport layer (10d) are laminated on a conductive support body (10a) in this order, wherein a layer configuring an outermost surface of the electrophotographic photoreceptor (10) contains composite structure particles in which a core material is inorganic particles, and the inorganic particles are coated with tin oxide doped with aluminum, and an average particle diameter of primary particles of the composite structure particles is 50 nm to 200 nm.
