PURPOSE:To obtain a photoconductive film high in sensitivity by incorporating a specified organic photoconductive compound. CONSTITUTION:The photoconductive film contains at least one of the hydrazone compounds represented by formulae I, II, and III in which each of R1-R6 is H atom. or a monovalent organic residual group, such as straight or branched alkyl, aryl, aralkyl group, halogen atom., alkoxy, or aryloxy group, and they may be same or different as or from each other, and each of R1 and R2 may combine with each other to form an condensed polycyclic aromatic ring, and each of R5 and R6 may combine with each other to form an N-containing ring, and A is an optionally substituted aromatic hydrocarbon group or aromatic heterocyclic group, thus permitting the obtained photoconductive film to be highly sensitive. |
