An electrophotographic photosensitive member having no interference fringes during image formation and having no image defects such as black spots, white spots, and ghosts, a process cartridge having the electrophotographic photosensitive member, and an electrophotographic process. It is to provide a device. SOLUTION: In an electrophotographic photoreceptor having a charge generation layer and a charge transport layer on a support in this order, the charge generation layer contains more than 2 parts by weight of a charge generation substance per 1 part by weight of a binder resin. Not more than 10 parts by mass, and the maximum height of the surface roughness of the support (RmaxD) and the 10-point average roughness (R z), arithmetic average roughness (Ra) and average spacing of irregularities (S An electrophotographic photosensitive member, wherein m) satisfies the following conditions, a process cartridge having the electrophotographic photosensitive member, and an electrophotographic apparatus. 1.2 μm ≦ RmaxD ≦ 5.0 μm 1.2 μm ≦ Rz ≦ 3.0 μm 0.15 μm ≦ Ra ≦ 0.5 μm 30 μm <Sm ≦ 80 μm |
