PURPOSE:To obtain the titled material having a high sensitivity especially at a wavelength range of a semiconductor laser by incorporating at least one kind of the compds. shown by the formula to an organic photoconductive substance. CONSTITUTION:The titled material comprises the compd. shown by the formula to the organic photoconductive substance. In the formula, R1, R2 R4 and R5 are each a hydrogen atom or a substd. or an unsubstd. alkyl group, R3 is a hydrogen atom, a halogen atom or a substd or an unsubstd. alkyl group, R1-R5 are each a hydrogen atom or an alkyl group, and may be same to or different to each other. A and B are each an oxygen atom or a sulfur atom, X is anion. And then, the electrophotographic film used in the titled material is prepared by coating the titled material on the polyethylene terephthalate film provided a deposited film composed of an indium oxide thereon followed by drying it. Thus, the prescribed film gives the max. adsorption at a range of oscillating the laser. |
