PURPOSE:To provide the photosensitive body which has high sensitivity, excellent stability in repetitive operations and sensitivity in a light wavelength region of a wide range by providing a photosensitive layer contg. a specific compd. on a conductive base. CONSTITUTION:The tetra-2,3-quinoxaline porphyrazine compd. expressed by the formula I is incorporated into the photosensitive layer provided on the conductive base. In the formula, R1-R4 denote groups selected from the groups consisting of a halogen atom, hydroxyl group, etc., and the group selected from the groups consisting of -NR5R6 (where R5, R6 denote a residual univalent org. group or form a ring together with the adjacent nitrogen atom); a-d denote 0-4 integer; M denotes a metal selected from metals and transition metals of group IIIA and group IVA. X, Y denote a halogen atom, oxygen, etc., and the group selected from the groups expressed by -OSiR7R8R9 (where R7-R9 denote residual univalent org. groups); m, n denote the number of pieces of X, Y. The photosensitive body having the high sensitivity, the excellent stability in the repetitive operations and the sensitivity in the light wavelength region of the wide range is obtd. in this way. |
