PURPOSE:To obtain a photoconductive film high in sensitivity and an electrophotographic sensitive body using it by incorporating at least one kind of trisazo pigment having a structure represented by a specified formula. CONSTITUTION:The photoconductive film contains at least one of the novel bisazo pigments represented by formula I in which Z is an atomic group necessary to form an optionally substituted aromatic hydrocarbon ring or hetero ring by condensing with a pyrazine ring; and A is represented by formula II, thus permitting the photoconductive film to be enhanced in sensitivity and the electrophotographic sensitive body having said film to be obtained. |
