Process to form light-receiving member with outer layer made by alternately forming and etching
First Claim
1. A process for producing a light-receiving member which comprises the steps of:
- (a) forming an outer layer on the surface of a light-receiving layer, said light-receiving layer supported by a substrate, said outer layer comprising a non-single-crystalline material containing silicon atoms and at least one kind of carbon atoms, oxygen atoms or nitrogen atoms;
(b) etching the surface of the outer layer so as to remove a portion of the outer layer;
(c) forming a second outer layer of a non-single crystalline material containing silicon atoms and at least one kind of carbon atoms, oxygen atoms or nitrogen atoms on the surface of the remaining outer layer after the step (b) is conducted; and
(d) etching the surface of the second outer layer formed in the step (c), to form a surface layer on the light-receiving layer.

Abstract
In a reactor capable of reducing an internal pressure thereof, a non-single-crystalline material layer containing at least one kind of carbon atoms, hydrogen atoms or nitrogen atoms is formed and etched on a non-single-crystalline photoconductive layer mainly composed of silicon atoms, formed on a substrate, under application of a high-frequency power of 50 MHz to 450 MHz, and the formation and the etching are alternately repeated plural times to form a surface layer.
A light-receiving member having such a surface layer does not damage cleaning performance over a long period of time, hardly allows adhesion of corona discharge products, and can be free from faint images, smeared images and uneven image density even if no heating means for the drum is provided.
