PURPOSE:To enhance sensitivity of a photosensitive body by forming an electrostatic charge generating layer and a charge transfer layer each having a specified composition on a conductive substrate. CONSTITUTION:A laminate type electrophotographic sensitive body high in sensitivity can be obtained by forming on the conductive substrate the charge generating layer containing the polycyclic quinone type pigment represented by formula (I), and the charge transfer layer containing the hydrazone derivative represented by formula (II) in which each of R1, R2, R3, R4, is optionally substituted alkyl or such aryl or an atomic group necessary to complete a 5- or 6-membered ring together with the adjacent N atom; each of R5, R6 is H, halogen, nitro, optionally substituted alkyl or alkoxy, such aryloxy, such acyl, or such amino; and R is such arylene. |
