PURPOSE:To obtain a photosensitive body superior in characteristics after repeated uses and durability by using a specified bisazo pigment. CONSTITUTION:The photosensitive layer to be formed on a conductive substrate contains one of the bisazo compounds represented by formulae I and II in which X is -O-, -S-, or the like; each of R1-R3 is H, alkyl, or the like; each of Y1 and Y2 is H, halogen, or the like; A is a coupler residue necessary for forming the bisazo pigment; and n is 0 or 1. This azo pigment can be used in various manners; for example, the bisazo pigment is dispersed into a binder, the conductive substrate is coated with this dispersion, and the obtained layer is used for a photoconductive layer, or this bisazo pigment is dispersed as the electric charge generating agent into a charge transfer material, and the conductive substrate is coated with the mixed dispersion to form the photosensitive layer. |
