PROBLEM TO BE SOLVED: To provide an overcoat layer of an electrophotographic photoreceptor having improved chemical, mechanical and electroconductive properties and to provide an electrophotographic photoreceptor. SOLUTION: The overcoat layer comprises a rheologic modifier and a polymer resin comprising one or a combination of two or more selected from a urethane resin, a urethane-epoxy resin, an acrylated-urethane resin and a urethane-acrylic resin. The electrophotographic photoreceptor includes the overcoat layer, a charge transport material, a charge generating material and an electroconductive substrate. The polymer resin is preferably the urethane-acrylic resin and the rheologic modifier is preferably a nonionic rheologic modifier. COPYRIGHT: (C)2003,JPO
