A photoconductive member, comprises a support for a photoconductive member and an amorphous layer which is constituted of silicon atoms as matrix containing at least one of hydrogen atom and halogen atom and exhibits photoconductivity, said amorphous layer having a layer region containing carbon atoms in at least a part thereof, the content of the carbon atoms in said layer region being distributed unevenly in the direction of the thickness of said layer.
An electrophotographic apparatus includes an amorphous silicon electrophotographic photosensitive member thereon having a conductive base, a photoconductive layer thereon containing carbon atoms, a content of which is minimum adjacent a position closest to the surface layer and/or other atoms, and a surface layer thereon containing 40-90 atomic % of carbon atoms and/or other atoms; a light source for electric discharge driven through a pulse width modulation using a reference wave having a frequency of not higher than 10 kHz; a device for projecting information light onto the photosensitive member; and a driver for driving the photosensitive member relative to the light source at such a speed that a peripheral speed of the photosensitive member divided by the frequency of the reference wave is not more than 1 mm.
Electrophotographic photosensitive bodies which comprise a photosensitive layer on a conductive support, and which contain a wax having an ester group in their outermost layer, exhibit excellent durability and improved wear and printing resistance, without sacrificing their photosensitizability properties, such as chargeability and sensitivity, or ease and quality of application.
