PURPOSE: To obtain a good photoelectric conversion efficiency and stabilize characteristics in a continuous service, by forming a photoconductive layer containing a charge occurrence pigment and a specific charge transport dye between two electrodes.
CONSTITUTION: A photoconductive layer containing a charge occurrence pigment and a charge transport dye is installed between two electrodes. The charge transport dye is formed of a compound shown in expression I. In expression I, R1 and R2 are an alkyl group or a phenyl group in which a substituent group may be used, and n is an integer of 1 to 10, and A is a group shown in expression II and III. In expression II and III, R3, R4, R31 and R41 are the alkyl group or the phenyl group in which the substituent group may be used, and l or m are an integer 0 to 3, and R5, to R7, R51, R61 and R71 are an hydrogen atom, the alkyl group or the like. Also, an electric charge occurs in the charge occurrence pigment, and while an electron is moved to an anode, a hole is injected into the charge transport dye and is moved to a cathode. Thus, characteristics in a continuous service can be stabilized.
