(57) An electrophotographic photoreceptor having good sensitivity even when a protective layer is formed, a small increase in residual potential, a small potential fluctuation due to environmental changes, and stable electrophotographic characteristics. An object of the present invention is to provide a process cartridge having the electrophotographic photosensitive member and an electrophotographic apparatus. SOLUTION: In an electrophotographic photoreceptor having a conductive support, a photosensitive layer and a protective layer, the protective layer has two The photosensitive layer contains a compound obtained by polymerizing a hole transporting compound having one or more chain polymerizable functional groups, and has a molecular weight of 350 An electrophotographic photosensitive member containing the above-mentioned charge transport material, a process cartridge having the electrophotographic photosensitive member, and an electrophotographic apparatus. |
