Abstract

PURPOSE: To obtain the captioned photoreceptor which is capable of copying two- color originals in one copying process by providing photoconductive layers and photosensitive layers respectively on both surfaces of a transparent substriate and using the set of the specific photosensitive layers of different photosensitive wavelength regions as the abovementioned both photosensitive layers.
CONSTITUTION: In the photoreceptor formed by providing a transparent electrode 2 and photosensitive layer 4 as well as a transparent electrode 2 and photosensitive layer 4' respectively on both sides of a transparent substrate 1, the photosensitive layer 4 (image exposure side) having, e.g., blue (or red) sensitivity and the photosensitive layer 4' (counter image exposure side) having panchromatic sensitivity are used in combination or the photosensitive layer 4 having blue sensitivity (having no red absorption) and the photosensitive layer 4' having red sensitivity (no blue absorption) are used in combination to form the photoreceptor.
