An electrophotographic photosensitive member hard to cause the problem of chatter and wear-out of the cleaning blade and the problem of a rubbing memory, and both a process cartridge and an electrophotographic apparatus having the photosensitive member are provided. The peripheral surface of the photosensitive member has a plurality of dimple-shaped concaves, a 10-point average roughness Rzjis (A) as measured by sweeping along the circumference of the peripheral surface of the photosensitive member is 0.3 to 2.5 μm, a 10-point average roughness Rzjis (B) as measured by sweeping along the generating line of the peripheral surface of the photosensitive member is 0.3 to 2.5 μm, a mean spacing of profile irregularities, RSm (C), as measured by sweeping along the circumference of the peripheral surface of the photosensitive member is 5 to 120 μm, a mean spacing of profile irregularities, RSm (D), as measured by sweeping along the generating line of the photosensitive member is 5 to 120 μm, and the value of a ratio (D/C) of the mean spacing of profile irregularities RSm (D) to the mean spacing of profile irregularities RSm (C) is 0.5 to 1.5. |
