Title:
ELECTROPHOTOGRAPHIC PHOTORECEPTOR
Document Type and Number:
WIPO Patent Application WO/2006/062256
Kind Code:
A1
Abstract:
An electrophotographic photoreceptor that while minimizing an absorption of short-wavelength image exposure at its surface layer, is capable of maintaining excellence in electrophotographic performance, such as resolving power. There is provided an electrophotographic photoreceptor comprising a conductive base material and, sequentially superimposed thereon, a photoconductive layer of non-single-crystal silicon film and a surface region layer of non-single-crystal silicon nitride film containing silicon and nitrogen atoms. The surface region layer includes a variation layer in which the constituent ratio of silicon and nitrogen atoms is varied and a surface layer in which the constituent ratio is unchanged. The variation layer and surface region layer contain an element of Group 13 of the periodic table, and in the content distribution of the element in the direction of the thickness of each of the layers, there is at least one maximum value.
