PROBLEM TO BE SOLVED: To provide an electorphotographic photoreceptor which is good in sensitivity in spite of formation of a protective layer, is little in an increase of residual potential and small in potential fluctuation by environment at change and makes it possible obtain stable electrophotographic characteristics, a process cartridge having the electrophotographic photoreceptor and an electrophotographic device.SOLUTION: The electrophotographic photoreceptor which has a conductive substrate, a photosensitive layer and a protective layer, has the protective layer containing a compound polymerized with a hole transferable component having ≥2 chain polymerizable functional groups within the same molecule and has the photosensitive layer containing a charge transfer material of ≥350 in molecular weight, the process cartridge having the electrophotographic photoreceptor and the electrophotographic device.
