    摘要： The present invention relates to an electrophotographic sensitive member comprising a photoconductive amorphous silicon carbide layer.An amorphous silicon layer has superior abrasion resistance, heat resistance, antipollution property, photosensitive characteristic and the like.However, an amorphous silicon layer itself has a low dark resistance, so that dopants, such as boron, are added thereto but a dark resistance of 10.sup.12 .OMEGA..multidot.cm or more required for the case where it is used as an electrophotographic sensitive member has never been obtained.The present inventors have found before that an amorphous silicon carbide layer has a large carrier-mobility and photoconductivity and its dark resistance of 10.sup.13 .OMEGA..multidot.cm or more can be easily obtained regardless of the existence of dopants and furthermore an electrophotographic sensitive member, which can be positively and negatively charged by the selection of the dopants, can be obtained. The present invention provides an electrophotographic sensitive member capable of improving the photosensitive characteristics and the like to improve electrophotographic characteristics, as desired, with an a-SiC layer as a substantial photoconductive layer and substantially without requiring a surface protective layer and a barrier layer.

    摘要： A light receiving member has a support and a light receiving layer. The support has an uneven-shaped surface of a plurality of spherical dimples, each dimple having an identical radius of curvature R and an identical width D, wherein the ratio D/R of the width D to the radius of curvature R is from 0.03 to 0.07. The light receiving layer is a multi-layered structure having an outer layer which formed from an amorphous material containing silicon atoms as the main constituent and at least one of hydrogen atoms and halogen atoms. The light receiving layer contains an inner layer of amorphous silicon which also contains germanium and/or tin and hydrogen and/or halogen.The light receiving member, when used with a coherent laser beam as an optical source, acts to prevent the occurrence of an interference fringe pattern during image formation.
