Abstract
An electrophotographic photosensitive member for forming a potential image utilizing the difference in voltage distribution resulting from the change in resistance of a photoconductive layer. The photosensitive member is featured in forming a high-contrast potential image by the use of amorphous silicon for the photoconductive layer.
Claims13
An electrophotographic photosensitive member adapted for use in an electrophotographic process in which a photoconductive layer having electrodes is subjected to imagewise exposure in the presence of a voltage to generate a difference in the distributed voltage between the exposed and unexposed areas due to the change in resistance in the exposed area of said photoconductive layer thereby creating a potential image by the difference in surface potential corresponding to said difference in the distributed voltage, which comprises a photoconductive layer principally composed of amorphous silicon, a number of electrically isolated conductors formed on the surface of the photoconductive layer, and one pair of electrodes arranged at the photoconductive layer, said one pair of electrodes arranged in such a way that a potential applied between said one pair of electrodes can be distributed through each of said isolated conductors.
