Abstract
An electrophotographic photosensitive member is disclosed which has a change layer consisting of five or more a-SiC intermediate layers, provided between an a-Si photoconductive layer and an a-SiC surface layer. Where two layers contiguous to each other in which C/(Si+C) is from 0.35 to 0.65 are selected from among the a-SiC intermediate layers included in the change layer, the rate of increase between the C/(Si+C) of an a-SiC intermediate layer on the photoconductive layer side and the C/(Si+C) of an a-SiC intermediate layer on the surface layer side (i.e., the rate of increase between layers) is 19% or less.
