A copying machine generally has a photosensitive drum (photosensitive drum), and the surface of the photosensitive drum generally has a two-layer structure of a charge carrier (hereinafter referred to as carrier) generating layer and a carrier transporting layer. Many materials have been developed for the carrier generation layer and the carrier transport layer. As the material, a material formed by mixing a low molecular material with a polymer binder and forming a film is often used. As a photoconductive polymer serving as the polymer binder, a pendant polymer such as polyvinyl carbazole is known. It is known that in a pendant polymer, the quantum yield of carrier generation and the carrier mobility are low because excitons generated by photoexcitation are trapped in an associated portion of a pendant group or the like. For this purpose, low-molecular compounds have been molecularly dispersed in high-molecular compounds to increase the generation and movement of carriers from the low-molecular compounds. Further, it is known that a conjugated polymer known as a conductive polymer also exhibits photoconductivity by photoexcitation.
