PURPOSE:To enhance photosensitivity and repetition characteristics by incorporating at least one of specified hydrazone compounds in a photosensitive layer. CONSTITUTION:The photosensitive layer 20 formed on a conductive base body 1 contains an electric charge transfer material 5 at least one of the hydrazone compounds represented by formula I in which each of R1-R12 is H, halogen atom, hydroxy, alkoxy, optionally substituted alkyl, such aryl, or amino group; and each of R13-R16 is optionally substituted alkyl, such aryl, or such aralkyl group; X is S or Se atom; and each of (n) and (m) is an integer of 0-2, thus permitting the obtained photosensitive body to be high in sensitivity and superior in repetition characteristics. |
