ABSTRACT:
An improved light receiving member for use in electrophotography having a light receiving layer provided with a charge carrier generation layer (hereinafter referred to as "CGL") and a charge carrier transport layer (hereinafter referred to as "CTL"), the CGL being formed of a non-single-crystal material composed substantially of silicon atom as the main constituent atom and at least one kind selected from hydrogen atom and halogen atom and the CTL being formed of a Non-Si(H,X) material containing carbon atom and a conductivity controlling element selected from the group consisting of boron, aluminum, gallium, indium and thallium belonging to group III of the Periodic Table or from the group consisting of phosphorus, arsenic, antimony and bismuth belonging to group V of the Periodic Table in an uneven state in the thicknesswise direction, and optionally at least one kind selected from oxygen atom and nitrogen atom in this order from the side of a substrate.
The above light receiving member is that electrical, optical and photoconductive properties are always substantially stable scarcely depending on the working circumstances, that is excellent against optical fatigue, causes no degreadation upon repeating use and that is excellent in durability and moisture-proofness and exhibits no or scarce residual potential.
