ABSTRACT:
An electrophotographic photoconductor is disclosed, which comprises an electroconductive layer, on which are formed in order, a photoconductive layer, a charge retention layer and a protective layer, optionally an adhesive layer between the charge retention layer and the protective layer, the charge retention layer comprising a silicone resin which comprises: (a) 50 wt. % to 80 wt. % of silicone and oxygen, (b) 10 wt. % to 30 wt. % of carbon, (c) 1 wt. % to 10 wt. % of hydrogen, and (d) 1 wt. % to 10 wt. % of nitrogen. The photoconductive layer may comprise an As-Se alloy, in which case, it is preferable that the amount of As be in the range of 33 wt. % to 38 wt. % and the balance thereof be Se in the As-Se alloy. Preferably the adhesive layer comprises a hardened material containing a metal alkoxide.
