Electrophotographic photosensitive member having barrier layer comprising microcrystalline silicon containing hydrogen |
摘要 |
In an electrophotographic photosensitive member according to the present invention, a barrier layer is formed on a conductive substrate, and a photoconductive layer on the barrier layer. Formed of microcrystalline silicon, the photoconductive layer is highly sensitive to long-wavelength light. 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.
