Abstract (en)
[origin: EP0696763A1] 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<5> OMEGA .cm to 10<1><0> OMEGA .cm when a loading pressure of 100 Kg/cm<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. <MATH>
