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 carbazole compound shown in expression I. In expression I, R<1> and R<2> are a hydrogen atom, an alkyl group, an alkoxy group or the like, and R<3> is a group shown in expression II. In expression II, R<4> is the hydrogen atom, a halogen atom, the alkyl group or the like. When light is emitted into the photoconductive layer, an electric charge occurs in the charge occurrence pigment in the photoconductive layer, and while an electron is moved to an anode, a hole is injected into the charge transport dye and is moved to a cathode through the charge transport dye. Thus, the uniform photoconductive layer can be formed. |
