ABSTRACT:
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.
