PURPOSE:To prevent generation of flow in a picture image, to improve the quality of the image, and to stabilize the characteristics of a photosensitive body by forming an intermediate layer comprising optional amorphous material layers wherein the surface of the amorphous material layers are smoothened. CONSTITUTION:A surface of an intermediate layer 37 is smoothened by polishing in a midway of film forming stage of plural amorphous material layers 36-38, and all film forming processes are completed thereafter. Thus, the surface roughness of a photosensitive body 34 is improved and the surface area of the photosensitive body 34 is reduced substantially. The absolute amt. of deposition of materials produced by Corona discharge is reduced, and removal of the deposited material produced by the Corona discharge is facilitated, so deterioration of surface resistance due to long time use is avoided. Moreover, exposure of free bonds formed by the polishing on the surface of the photosensitive body 34 is prevented because a surface protecting layer 38 contg. C atoms. and having high carrier transfer characteristic and high potential retaining effect is formed on the front polished photoconductive layer 37. Thus, the characteristics of the photosensitive body are improved, generation of flow in the picture image is prevented, and the quality of image is improved. |
