PURPOSE:To obtain good light resistance, high sensitivity without causing any defect on the image, and high durability by incorporating a specified hydrazone compound and a specified pyrazole compound as an electric charge transfer material to be added to a charge transfer layer. CONSTITUTION:The electrophotographic sensitive body is a laminate type formed by laminating a charge generating layer and the charge transfer layer on a conductive supporting body, and the charge transfer material to be added into the charge transfer layer contains at least one of the hydrazone compounds represented by formulae (Ia) and (Ib), and at least one of the pyrazole compounds represented by formula II, and in these formulae, R1 is methyl group or the like; each of R2 and R3 is H or the like; R4 is methoxy group or the like; and R7 is methyl or ethyl group, thus permitting electrophotographic characteristics to be improved and light resistance to be remarkably enhanced. |
