PHOTOSENSITIVE BODY FOR ELECTROPHOTOGRAPHY, PROCESS CARTRIDGE, AND ELECTROPHOTOGRAPHIC APPARATUS |
摘要 |
<p>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 alpha and beta , 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).</p> |
