PURPOSE:To distinguish a photosensitive body in sensitivity and to enhance general electrostatic characteristics by incorporating a specified azo pigment in a photosensitive layer. CONSTITUTION:The photosensitive layer formed on a conductive supporting body contains at least one of the azo pigments represented by formula I in which each of R1 and R2 is H, halogen, optionally substituted alkyl, aralkyl, aryl, a condensed polycyclic group, or a heterocyclic group, and R1 and R2 may be formed a ring together with them, (n) is 1-4, thus permitting general electrostatic characteristics, especially, sensitivity to be enhanced. |
