PROBLEM TO BE SOLVED: To provide a composition for the formation of a surface protective layer of an organic photoreceptor with improved adhesion strength and excellent wear resistance and electric characteristics, and to provide an organic photoreceptor. SOLUTION: The organic photoreceptor is composed of a conductive supporting body, a photosensitive layer formed on the surface of the conductive supporting body, and a surface protective layer formed by coating the surface of the photosensitive layer with the composition for the formation of the surface protective layer containing an organic silane compound, an acrylic polymer, polyvinylbutyral and a solvent and then heat treating the composition. As for the acrylic polymer, a methylmethacrylate-methacryl acid copolymer is used. As for the solvent, a cosolvent of water and one or more alcoholic solvents selected from a group comprising methanol, ethanol, butanol and isopropanol is used. COPYRIGHT: (C)2004,JPO
