Electrophotographic photoconductor and a method for forming the same

Abstract

An electrophotographic photoconductor comprising a conductive support, an undercoating layer provided on the conductive support and a photosensitive layer provided on the undercoating layer, in which the undercoating layer comprises a needle-like titanium oxide particles and a binder resin. The needle-like titanium oxide particles in the undercoating layer show a volume resistance in the range from 10.sup.5 .OMEGA..multidot.cm to 10.sup.10 .OMEGA..multidot.cm when a loading pressure of 100 Kg/cm.sup.2 is applied and have a short axis S having a length of 0.5 .mu.m or less and a long axis L having a length of 10 .mu.m or less and the aspect ratio of L/S ranging from 2 to 10. Further, the needle-like titanium oxide particles are contained in the undercoating layer in the range from 50 wt % to 95 wt % and the surface thereof remains untreated.
