Abstract: An electrophotographic photosensitive material having a long lifetime can be provided by forming an amorphous silicon layer having a thickness of 0.01-0.08 .mu.m on the photoconductive layer on the electrically conductive substrate in the said material without changing the characteristics of the photoconductive layer.
