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