A photo conductor has a protective surface layer whereon at least a carrier generation layer and a carrier transport layer are provided onto a conductive base. The protective surface layer includes a first protective surface layer using a hydrocarbon gas-based amorphous carbon with an ion implantation layer, and a second protective surface layer using a hydrocarbon gas-based amorphous carbon without an ion implantation layer.

Photo conductor, image forming apparatus, and method for producing photo conductor

A thin film EL device having high electroluminescent efficiency, a low operating voltage, and a long lifetime. A thin film EL device of the present invention uses, as a luminescent layer, a charge-transport luminescent material that has, within a molecule, a portion contributing to charge transport and a portion contributing to luminescence where at least two molecular orbitals contributing to luminescent transition are localized.
