ABSTRACT:
An organic photosensitive member for electrophotography is formed of a cylindrical supporting member and an organic photosensitive layer on an outer surface of the supporting member. The supporting member is formed of a material of 10.sup.4 ohm.cm in volume resistivity containing a cross-linking type polyphenylenesulfide resin as a main component, and a highly conductive carbon black of 10.sup.-1 ohm.cm or less in volume resistivity. Thus, the supporting member has a light weight with good productivity and good chemical and thermal resistance. The supporting member can be made with dimensional accuracy despite its thin and long shape, and also has a uniform surface roughness, stable surface quality and good adhesion.
