PURPOSE:To obtain a photosensitive body having stable electric characteristics, improved sensitizing effect, crystallization retarding effect, adhesion and flexibility of a photoconductive layer by providing a layer contg. fine particles of a specified disazo pigment dispersed in an insulative resin between a photoconductive supporting body and an Se photoconductive layer. CONSTITUTION:An intermediate layer contg. a pigment expressed by the general formula I : [wherein A is a group expressed by the formulas II, III, and IV; X is an aromatic ring such as benzene ring, naphthalene ring, etc. heterocyclic ring such as indole, carbazole, benzofuran ring, etc. or having a substituent such as halogen in said ring; Ar<1> is an aromatic ring such as benzene ring, etc. or substituted products thereof, heterocyclic ring such as dibenzofuran ring or substituted products thereof; Ar<2>, Ar<3> are aromatic rings such as benzene ring, heterocyclic ring such as dibenzofuran ring, or substituted products thereof; substituents of Ar<1>, Ar<2>, and Ar<3> are halogen, lower alkyl, NO2, CN, sulphonic acid, etc.; R<1>, R<3> are H, lower alkyl, COOH or its ester] dispersed in an insulative resin is provided. In this way, a superior photosensitive body for electrophotography is obtd. |
