PROBLEM TO BE SOLVED: To obtain a photoreceptor excellent in producibility, which is inter changeable, in electrical properties, with the conventional laminated electrophotographic sensitive body and has a desired image characteristic by incorporating an amount of a specified range, based on a binding resin, of an electron-transporting material into the photosensitive layer. SOLUTION: An electric charge generating materials 2, an electron- transporting material and a hole-transporting material together with a binding resin are incorporated in a photosensitive layer 4, wherein the electron- transporting material is added within an amount of 1-2 parts by mass per 1 part by mass of the binding resin. In this case, it is, especially, preferable to incorporate the hole-transporting material into the photosensitive layer 4 in an amount of 0.1-0.5 parts by mass per 1 part by mass of the binding resin. Diphenoxy compounds and/or fluorenylidene malononitrile compounds are suitable as the electron-transporting materials.
