    摘要： An electrophotographic photosensitive member having an insulating layer overlaid on the one side of an amorphous photoconductive layer is characterized in that said photosensitive member further comprises two layers: a charge injection layer and a subsidiary charge injection layer overlaid on the other side of the photoconductive layer with the subsidiary charge injection layer being interposed between the photoconductive layer and the charge injection layer, said subsidiary charge injection layer having a lower free charge density than that in the photoconductive layer and being able to make it easy to inject an amount of electric charge from the charge injection layer into the photoconductive layer whereas said charge injection layer has a higher free charge density than that in the photoconductive layer and serves as a main supply source of the electric charge to be injected into the photoconductive layer.
