PURPOSE:To obtain an photoconductive film high in sensitivity by incorporating a specified trisazo pigment. CONSTITUTION:The photoconductive film contains at least one of the trisazo pigments represented by formula I in which A is a group, such as formula II or III; each of B1-B4 is H atom, lower alkyl group, or the like; X is an atomic group necessary to condense with the benzene ring with which a hydroxy group and Y combine in formula I, and to form an aromatic ring or heterocyclic ring; Z is an atomic group necessary to condense with the pyrazine ring and to form an aromatic ring or heterocyclic ring; and R in formulae II and III is H atom, alkoxy group, or the like, thus permitting the obtained photoconductive film to be high in photoconductivity. |
