    摘要： An electrophotographic photosensitive member, comprising a support and a photosensitive layer disposed on the support. The photosensitive member has a surface layer comprising a siloxane polymer which comprises at least two polysiloxane units each independently represented by a formula (1) (shown in the specification) and has a molecular structure such that adjacent two polysiloxane units of the formula (1) are connected with each other at their side chains by --O--Pc--CO--O-- where Pc denotes a polycarbonate chain. Such a molecular structure of the siloxane polymer is effective in improving lubricating properties of the surface of the photosensitive member while retaining a mechanical strength thereof.

    摘要： The present invention provides an electrophotographic photosensitive member capable of maintaining high transfer efficiency without causing large transfer current for a long-term use, obtaining an excellent image, and achieving those effects especially when being applied to a color electrophotographic apparatus. The invention also provides a process cartridge and an electrophotographic apparatus each having such a photosensitive member. The present invention includes an electrophotographic photosensitive member having a photosensitive layer on a support, a surface layer containing diorganopolysiloxane having specific repeating structure units α and β, and having a weight-average molecular weight of 1,000 to 1,000,000; in which a content of the diorganopolysiloxane in the surface layer is 0.01 to 20% by weight based on the entire weight of the surface layer (except in the case where the surface layer contains fluorine atom-containing resin particles).
