PURPOSE:To permit provision of good UV resistance, high sensitivity and high durability to an electrophotographic sensitive body having layers contg. an electric charge generating material CGM and charge transfer material CTM by incorporating a specific compd. into said body. CONSTITUTION:This electrophotographic sensitive body which has the layers contg. the charge transfer material and charge generating material on a conductive base is the electrophotographic positive charge sensitive body contg. the compd. expressed by the formula. In the formula, A denotes an oxygen, sulfur atom or imino group. R1 denotes an aryl group, allyl group, R denotes alkyl, amino, nitro and alkoxy substituting groups which substitute hydrogen or halogen atom, n is 0 or 1, 2. The amt. of the compd. to be added is 0.1-100wt%, more preferably 1-50wt%, more particularly preferably 5-25wt% by the weight of the charge transfer material (CTM) in the charge generating layer (CGL) when said compd. is used in CGL. Said amt. is 0.1-100wt%, more preferably 1-50wt% by the weight of the binder resin in a protective layer (OCL) when the compd. is used in OCL. |
