PURPOSE:To obtain the titled body having an excellent repeating stability by coloring a protective layer in the titled body having the protective layer. CONSTITUTION:Optical-quality of charge removing light which reaches to the photoconductive layer is selected by dispersing a coloring matter in the protective layer at the time of forming the protective layer on the photosensitive surface, thereby improving repeating characteristic. The titled body having improved anti printing property as well as carrier transferability is obtd, by adding the coloring matter to the protective layer, thereby preventing deterioration of the characteristics of the titled body due to the protective layer. The protective layer is colored by the coloring matter having preferably an absorping peak at a short wavelength range of the region of about 500nm. Methyl red having to absorping peak at 450-550nm or rose bengal having its absorping peak at 558nm is exemplified as the prescribed coloring matter. |
