Electrophotographic sensitive body

Abstract

Abstract PURPOSE:To increase the sensitivity of a sensitive body by successively laminating a blocking layer of microcrystalline silicon,a photoconductive layer of microcrystalline silicon and a surface layer on a support and by forming a region contg. carbon or the like in the photoconductive layer on the surface layer side. CONSTITUTION:A blocking layer 2, a photoconductive layer 3 and a surface layer 4 are successively laminated on an electrically conductive support 1. The blocking layer 2 is made of microcrystalline silicon contg. a group III or V element and C, O or N, and the concns. of the group III or V element and C, O or N are made higher in the lower layer 2a on the support 1 side. The photoconductive layer 3 is made of microcrystalline silicon contg. a group III or V element and C, O or N, only the upper layer 3a close to the surface layer 4 contains C, O or N, and the lower layer 3b does not contain C, O or N. Since microcrystalline silicon is used and the group III or V element and C, O or N are properly incorporated in to the layers, the resulting sensitive body can be provided with superior electrostatic charging performance, sensitivity and high wear resistance.
