PURPOSE:To prevent the formation of interference fringes of light and to form an excellent image by roughening the surface of a photosensitive layer with a refractive index (n) formed on the surface of the base of an electrophotographic sensitive body to roughness more than lambda/(4n) (lambda: wavelength of light). CONSTITUTION:The photosensitive layer 2 which has a waving surface 2a as shown in a figure is formed on the base 1. The refractive index of the photosensitive layer 2 is denoted as (n) and the value of the roughness 4 is set to >=lambda/(4n) (lambda: wavelength of light). The photosensitive layer 2 uses selenium or CdS, but powder like CdS is disperesed in binding resin. When an insulating layer is formed on the selenium or CdS for protection, the selenium or CdS is flattened and the insulating layer may be roughened. Thus, the formation of interference fringes of incident light is prevented to form an excellent image. |
