摘要：<p>An electrophotographic photosensitive member is constituted by a support and a photosensitive layer disposed on the support. The photosensitive member has a surface layer comprising a silixane 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. <IMAGE></p>
