Summary:PURPOSE:To enhance sensitivity of the photosensitive body and potential stability at the time of repeated uses by incorporating a specified azo pigment. CONSTITUTION:The photosensitive layer of this photosensitive body contains the azo pigment represented by formula I in which Ar1 is an aromatic hydrocarbon group or heterocyclic group optionally combined through a bonding group; Ar2 is an aromatic hydrocarbon group or heterocyclic group; R1 is H, alkyl, or the like; X is an atomic group necessary to form a desired ring; =Y is =N-NR2R3, =N-Ar3, or the like; each of R2 and R3 is H, alkyl, or the like; Ar3 is an aryl or heterocyclic group; and n is 1 - 4. It is preferred to form the photosensitive layer having a laminate structure comprising an electric charge generating layer containing the pigment of formula I, embodied by formula II and a charge transfer layer containing a desired material, such as the hydrazone compound embodied by formula III.
