PURPOSE:To improve electrostatic charge retentivity, repeating use characteristics, printing resistance, etc., of a photosensitive body and to obtain a superior image free from fog by forming a resin layer contg. a specified hydrazone compd. as an undercoat layer on a conductive substrate. CONSTITUTION:The undercoat layer formed on the conductive substrate is composed of a resin contg. a hydrazine compd. represented by the formula in which R1 is H, methyl, or phenyl; R2, R3 are each alkyl, aralkyl, or aryl, or both may unite to form a ring; n is 1 or 2; and A is an aromatic or aromatic heterocyclic group. Such an undercoat layer may be formed in a various film thicknesses, and a superior surface smoothness can be obtained, thus permitting the charge retentivity, repeating use characteristics, and printing resistance of the photosensitive body to be improved, and a superior image free from fog to be obtained. |
