Photosensitive member and electrophotographic apparatus using same.

摘要

An electrophotographic photosensitive member (101) for being charged by a charging member (102) which is contacted thereto and which is supplied with an oscillating voltage (103) includes a photosensitive layer (101b); a base member (101a) for supporting the photosensitive layer (101b); a portion for receiving driving force; and total weight divided by total volume of the photosensitive member (101) is not less than 0.65 g/cm<2>. This structure avoids vibrations of the photodrum (101) when an AC-fed contact charger (102) is used. <IMAGE>
