PROBLEM TO BE SOLVED: To obtain an electrophotographic photoreceptor excellent in printing durability, wear resistance, scratch resistance or the like for repeated use by incorporating a specified wax into the surface of a photosensitive layer and using a specified compd. as a charge transfer agent. SOLUTION: In this electrophotographic photoreceptor produced by forming a photosensitive layer on a conductive supporting body, the outermost layer of the photosensitive layer contains a wax having ester groups, and a compd. having a stilbene skeleton is used as a charge transfer agent. The wax having ester groups is produced from a carboxylic acid and an alcohol as the source components, and at least either the carboxylic acid or the alcohol preferably has >=12 carbon atoms, further preferably has >=12 and <=40 carbon atoms. The larger the number of carbon atoms, the wax has the higher melting point and better mechanical characteristics, however, the wax is easily precipitated in a coating liquid. Therefore, the number of carbon atoms in the aforementioned range is preferable. The compd. used as a charge transfer agent is a compd. having a stilbene skeleton.
