Photoconductive member with doped and oxygen containing amorphous silicon layers

摘要

A photoconductive member comprises a support for a photoconductive member and an amorphous layer containing an amorphous material comprising silicon atom as a matrix and having photoconductivity, said amorphous layer comprising a first layer region containing oxygen atom as a constituent atom, the oxygen atom being distributed continuously in the direction of the layer thickness and enriched at the support side, and a second layer region containing an atom of the group III of the periodic table as a constituent atom, said first layer region being internally present at the support side in the amorphous layer, and the layer thickness TB of said second layer region and a layer thickness T resulted from subtracting TB from the layer thickness of the amorphous layer satisfying the relation, TB/T
