An image-forming member for electrophotography and a manufacturing method for the same and an electrostatic photocopying machine are disclosed. The image-forming member comprises an organic photoconductive layer formed on a conductive substrate and a protective layer formed on the organic photoconductive layer. Hollows such as pinholes and cracks in the organic photoconductive layer are filled with insulating material, so that the organic photoconductive layer surface becomes even and thereby the protective layer such as a carbonaceous film having high hardness is formed on the organic photoconductive layer with a surface of the protective layer even such that foreign matters can not gather thereon. Alternatively, hollows such as pinholes and cracks in a protective layer are filled with insulating material. Thereby the protective layer surface is made even. Because of evenness and hardness of the protective layer, the image-forming member is immune to wear or scratches, and consequently clear images having no image flow, blur of images, white strips, and voids are obtained on copying sheets with an electrostatic photocopying machine utilizing the image-forming member.
