Claims
- 1. An electrophotographic sensitive member comprising an amorphous silicon photoconductive layer and an amorphous silicon carbide surface layer formed on a substrate in this order, characterized in that an intermediate layer, of which carbon-content is gradually increased in the direction of layer-thickness, is formed in a thickness of 10 to 2,000 .ANG. between said both layers, a carbon-content, that is a value of x in Si.sub.l-x C.sub.x on a boundary surface of said intermediate layer and said photoconductive layer being within a range of 0<x.ltoreq.0.45, and a carbon-content, that is a value of y in Si.sub.l-y C.sub.y on a boundary surface of said intermediate layer and said surface layer being within a range of 0.5.ltoreq.y.ltoreq.0.9.
- 2. An electrophotographic sensitive member as set forth in claim (1), in which the carbon-content of the amorphous silicon carbide surface layer is not substantially varied in the direction of layer-thickness.
- 3. An electrophotographic sensitive member as set forth in claim (1), in which the carbon-content of the amorphous silicon carbide surface layer is increased in the direction of layer-thickness towards the surface.
