摘要： An electrophotographic photoreceptor is disclosed which is constituted by a conductive substrate, a barrier layer formed thereon, and a photoconductive layer, formed on the barrier layer, for generating photocarriers upon radiation of light. A portion of the barrier layer is formed by alternately stacking first thin films consisting of amorphous or microcrystalline silicon containing an element which controls a conductivity type and second thin films, these having a band gap wider than that of the first thin film. A multilayered structure made up of the first and second thin films has a superlattice structure.

摘要： An electrophotographic photoreceptor is constituted by forming a barrier layer, a photoconductive layer, and a surface layer on an aluminum substrate drum, in the order stated. The photoconductive layer of this electrophotographic photoreceptor has a superlattice layer of a hetero-junction constituted by alternately stacking thin a-Si:H layers and thin .mu.c-SiC:H layers. In this superlattice structure, the optical bandgaps of the respective layers differ from each other, a-Si:H serves as a potential barrier, and .mu.c-SiC:H serves as a potential well. When light is radiated on the photoconductive layer, a large number of photocarriers are generated. The photocarriers having one polarity pass through the barrier by way of a tunneling effect, and propagate in the photoconductive layer.

摘要： 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.

The charge-generating layer of this electrophotographic photoreceptor has a superlattice structure of a heterojunction constituted by alternately stacking thin a-Si:H layers and thin .mu.c-SiC:H layers. In this superlattice structure, the optical bandgaps of the respective layers differ from each other, a-Si:H serves as a potential barrier, and .mu.c-SiC:H serves as a potential well. When light is radiated on the charge-generating layer, a large number of photocarriers are generated. The photocarriers having one polarity pass through the barrier by way of a tunneling effect, and propagate in the charge-generating layer. In addition, the charge-transporting layer is formed by a-Si:H or .mu.c-Si:H, and hence more easily enables allows photocarriers generated in the charge-generating layer to reach the conductive substrate.

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. The photoconductive layer is formed of a microcrystalline silicon layer, whose crystallinity varies all the way through its thickness. The higher the crystallinity of the microcrystalline silicon layer, the more distinguishable are the crystalline properties, the narrower is the optical band gap, and the higher is the sensitivity to long-wavelength light. If the crystallinity becomes lower, then the amorphous properties are enhanced, and the resistance is increased in proportion. Thus, the chargeability and the sensitivity to long-wavelength light of the microcrystalline silicon layer can be improved by varying its crystallinity in the photoconductive layer.
