Photosensitive body for electrophotography, process cartridge, and electrophotographic apparatus

The present invention provides an electrophotographic photosensitive member, the electrophotographic photosensitive member without transfer enhancement can be maintained for a long current high transfer efficiency and good image, even if it is in particular for a color electrophotographic apparatus, it may be without enhanced transfer current can be maintained long-term high transfer efficiency, good image. In addition, also provided a process cartridge and an electrophotographic image forming apparatus comprising the electrophotographic photosensitive member. The electrophotographic photosensitive member having a photosensitive layer on a support, wherein the surface layer of the electrophotographic photosensitive member contains diorganopolysiloxane, the diorganopolysiloxane containing a specific repeating structural units and α beta], a weight-average molecular weight of 1,000 to 1,000,000, the content of the diorganopolysiloxane in the surface layer relative to the total mass of the surface layer is 0.01 to 20 mass% (wherein the surface layer contains fluorine resin particles atoms except in the case).
