Claim 2
Dependent Claim
76 words
In an electrophotographic photoreceptor which comprises an electrically conductive support an at least one amorphous silicon photoconductive layer provided on said support, the improvement characterized in that the outermost surface of said photoreceptor consists of an amorphous silicon, and atoms/or ions of a metal selected from the group consisting of atoms of 3b, 4b, 5b, 6b, 7b, 8, 1b and 2b of the Periodic Table are present at or in close proximity to said outermost surface.
Claim 3
Dependent Claim
18 words
The photoreceptor of claim 1 wherein said outermost surface is a part of said amorphous silicon photoconductive layer.
Claim 4
Dependent Claim
24 words
The photoreceptor of claim 1 wherein said outermost surface is a part of an amorphous silicon layer other than said photoconductive amorphous silicon layer.
Claim 5
Dependent Claim
