ABSTRACT:
The present invention provides a single-layer type electrophotosensitive material comprising a conductive substrate and a photosensitive layer formed on the conductive substrate, wherein the photosensitive layer contains a phthalocyanine compound as an electric charge generating material, a hole transferring material and an electron transferring material in a binder resin, and that a difference in absolute value between a plus polarity sensitivity and a minus polarity sensitivity measured under the conditions of an exposure wavelength of 780 nm and an exposure energy of 1.0 μJ/cm2is not more thandelete-start id="DEL-S-00001" date="20110301" ?500delete-end id="DEL-S-00001" ?insert-start id="INS-S-00001" date="20110301" ?312insert-end id="INS-S-00001" ?V, and a reversal development type digital image forming apparatus using the electrophotosensitive material, which does not include a charge neutralizing step.
