ABSTRACT:
A method of improving image sharpness or image resolution on a dye sensitized electrophotographic photosensitive plate to be negatively charged before image light exposure and with use of positively charged toners, the method comprising applying ultraviolet light to the surface of the dye-sensitized photoconductive layer of the plate before the negative charging. Thereby, it becomes possible to use positively charged toners with excellent resultant image sharpness or resolution.
