PURPOSE:To form a photosensitive body effective for preventing occurrence of traps caused by an electrostatic charge transfer material due to light fatigue and accumulation of them, and for preventing rise of residual potential and stabilized in characteristics at the time of repeated uses by incorporating a specified azine compd. and a hydrazone compd. CONSTITUTION:A functionally separated type electrophotographic sensitive body contains in a charge transfer layer, and a nonseparated type contains in a photoconductive layer an azine compd. used as a light fatigue inhibitor and represented by formula [I], embodied by formula (1) (diphenylmethylenediazinodiethylaminobenzylidene), and a hydrazone compd. used as the charge transfer material represented by formula [II], preferably, embodied by formula (13), etc., and the functionally separated type contains the azine compd. in the charge transfer layer, preferably, in an amt. of 1-10wt%, and the hydrazone compd., preferably, in an amt. of 30-50wt%, and the nonseparated type contains the same amts. of them in the photoconductive layer itself. |
