PURPOSE:To prevent generation of image blurring by forming a surface layer of carbon as an essential component and incorporating an element forming a tetrahedron type bond therein. CONSTITUTION:The surface layer of an electrophotographic sensitive body consisting of a base 1, a photosensitive layer 2 and the surface layer 3 is made of the carbon as the essential component and the element forming the tetrahedron type bond is incorporated therein. The tetrahedron type bond of the carbon atoms is accelerated and the hardness of the film is greatly improved when the slight quantity of the atoms having 4 coordination number and capable of taking the tetrahedron type bond are incorporated into the film essentially consisting of the carbon. The optimum range of the content of the tetrahedron type bond forming element in the film is preferably <=0.5, more adequately <=0.2, most adequately <=0.1 with respect to carbon atoms. The generation of the image blurring is obviated even under any operating conditions. |
