ABSTRACT:
In an electrophotographic photosensitive member according to the present invention, a barrier layer is formed on a conductive substrate; a first layer of a photoconductive layer on the barrier layer, and a second layer on the first layer. Formed of microcrystalline silicon containing hydrogen, the first layer is highly sensitive to long-wavelength light. The second layer contains hydrogen and at least one element selected from carbon, oxygen, and nitrogen. The barrier layer is formed of microcrystalline silicon containing an element included in group III or V of the periodic table. The rectifying action of the barrier layer prevents carriers from being injected into the photoconductive layer from the substrate side. Containing carbon, oxygen, or nitrogen, the barrier layer has high dark resistance and chargeability.
