Abstract
The present invention relates to a photosensitive member which includes a photoconductive layer of amorphous silicon and an insulating layer formed thereover and including amorphous silicon, carbon and an element in Group III A of the Periodic Table. Carbon is included in an amount of about 35 to 65 atomic % at the outer most surface of the insulating layer and a minimum amount at the interface with the photoconductive layer. The Group III A element is included to control a majority carrier of the insulating layer to be a polarity opposite to the polarity of charging.
