Electrophotographic photosensitive member and electrophotographic apparatus

摘要

The present invention provides: an electrophotographic photosensitive member which has a photoconductive layer, an intermediate layer and a surface layer, wherein when the Si+C atom density in the surface layer is represented by D S × 10 22 atoms /cm 3 , the D S is 6.60 or more, and when the maximal value of H/(Si+H) in a distribution of hydrogen quantity in the photoconductive layer in a layer thickness direction is represented by H Pmax , the average value of the H/(Si+H) in the second photoconductive region is represented by H P2 , the D S and the H P2 satisfy the following expression (1) and the D S and the H Pmax satisfy the following expression (2); and an electrophotographic apparatus having the electrophotographic photosensitive member.
