PURPOSE:To obtain a color image with a high quality by providing the photosensitive layer of an optimum wavelength sensitivity on the photosensitive body surface of the length to form the developed image of the same color. CONSTITUTION:At a Y area image-exposed by a blue light B to form a Y developed image, a Se-Te type photosensitive layer is provided on an aluminum substrate. At both M area image-exposed by a green light G to form an M clear image and a C area image-formed by a red light R to form the C developed image, an As2Se3 system photosensitive layer is provided on an aluminum substrate. For the Se-Te system photosensitive material, the sensitivity to a B light of wavelength 400nm-500nm is more excellent than an As2Se3 system photosensitive material. On the other hand, to a G and an R light of 500nm-700nm, the As2Se3 system photosensitive material shows more excellent light sensitivity. Thus, a high quality electrostatic latent image is formed on the photosensitive body and the quality of a color image comes to be made satisfactory.
