Abstract
A layered type electrophotographic photoconductor includes an electroconductive support; and a photoconductive layer formed thereon, which photoconductive layer contains a charge generation layer and a charge transport layer, which are overlaid, with the charge generation layer containing a polyalkylene glycol and/or a derivative thereof and/or a crown ether, and the charge transport layer containing an antioxidant. Alternatively, an undercoat layer may be interposed between the electroconductive support and the photoconductive layer, with the undercoat layer containing a polyalkylene glycol and/or a derivative thereof and/or a crown ether, and the charge transport layer containing an antioxidant.
