Title:
PHOTOSENSITIVE BODY
Document Type and Number:
Japanese Patent JPH01185636
Kind Code:
A
Abstract:

PURPOSE: To improve the photosensitivity, the color sensitivity of the title body and the dispersibility of the coating solution of a pigment by mounting a photoconductive layer contg. a specified azo compd. on a conductive substrate.

CONSTITUTION: The dispersion stability of the pigment in the dispersing solution of the pigment, and the photosensitivity and the color sensitivity of the photosensitive body are improved by incorporating the pigment composed of the azo compd. shown by formula I in a photoelectric charge generating layer mounted on the conductive substrate of the photosensitive body. In the formula, B is a coupler shown by formulas IIWVII, Z is an atomic group constituting an aromatic carbon ring or an aromatic heterocyclic ring which may be substd., carbamoyl or sulfamoyl group, R1 is hydrogen atom, alkyl or amino group which may be substd., M is aryl group which may be substd.
