Abstract

A photoconductive composition comprises an electron-donating organic polymeric photoconductor (e.g. polyvinyl carbazole), from 0.15 to 0.45 mole, per mole of constituent photoconductor monomer, of an electron- accepting aromatic polycyclic nitro compound (e.g. tri- or tetra- nitro fluorenone), and from 0.2 to 4% by weight, based on the polymeric photoconductor, of phthalo cyanine or a nuclear-substituted derivative thereof. A photosensitive material comprising a layer of this photoconductive composition on a conductive substrate possesses a high saturation charge voltage, high sensitivity and much reduced residual potential, and has excellent mechanical, chemical and electric durabilities. A great number of clear and sharp prints having a high density and being free from fogging can be obtained when this photosensitive material is used repeatedly in electrophotography.
