PURPOSE:To improve the sensitivity and to decrease the fluctuation of the electrostatic charging potential in a durability test part by incorporating at last one kind among specific compds. into a charge generating layer. CONSTITUTION:An electrophotographic sensitive body which has specifically high sensitivity, lessens the decrease in the electrostatic charge potential in the stage of a durability test and lessens the residual potential is obtd. by adding the compd. expressed by the general formulas I -III into the charge generating layer in which a charge generating material is incorporated in a laminated type electrophotographic sensitive body having two layers; the charge generating layer contg. the charge generating material and charge transfer layer contg. a charge transfer material, on a conductive base body. The charge generating layer contains the compds. expressed by the above-mentioned general formulas I -III as essential components. The amt. of the compds. to be added is adequately <=10pts.wt., more preferably 0.01-2pts.wt. the charge generating compd. |
