发明名称 Photosensitive member for use in electrophotographic apparatus and method of manufacturing the same
摘要 A photosensitive member for use in an electrophotographic apparatus in which a bias potential is applied to the member during development. The member comprises a conductive support having at least one support edge and a photosensitive layer formed on the surface of the support and extending up to a point substantially coincident with the support edge. A tapered surface is formed at the extremity of the photosensitive layer adjacent to each support edge which extends from the top of the photosensitive layer to the support edge. The maximum angle between a tangent of the tapered surface and the surface of the conductive support is less then 45 DEG thereby preventing an edge effect by which a background smearing in the form of a black band may appear on copied paper obtained. Such a tapered surface can be easily formed through a vaporizing technique with a special masking in accordance with the present invention.
