PURPOSE:To obtain an electrophotographic sensitive body which has substantial photosensitivity particularly to long wavelength light such as laser light and obviates the generation of interference fringes by providing coarse boundary faces in parallel or coaxially with the surface into the photoconductive layer on a conductive substrate. CONSTITUTION:For example, Se is first deposited by evaporation on the conductive substrate 11 and the boundary face 13 thereof is roughened by wet or dry process etching or mechanical treatment in the stage of forming the photoconductive layer on said substrate. The photoconductive layer consisting of an Se-Te alloy is then thinly laminated thereon so that the surface 14 of the laminated photoconductive layer 12 reflects the rough surface of the layer 13. The laminated photoconductive layer 22 of which the boundary face between the layers 22-01 and 22-2 is roughened and the surface 24 of the layer 22-2 is also roughened is otherwise formed in the stage of forming a carrier transfer layer 221 and carrier generating layer 22-2 in this order on the base 21 surface. The apparent decrease in the photosensitivity with the coherent light such as laser light in particular owing to the interference between the light incident to the photosensitive bodies 10, 20 and the light reflected from the layer boundary faces 13, 14, 23, 234 is prevented by forming the photoconductive layer in the above mentioned manner. The electrophotographic sensitive body having substantial photosensitivity is thus obtd. |
