Abstract
In the electrophotographic process in which an image is formed by performing imagewise light exposure, toner development, toner image transfer and cleaning after charging a photoconductive photosensitive layer by direct current corona discharge, an organic photoconductive photosensitive layer in which the surface potential is saturated at 500 to 700 volts as the absolute value is used as the photosensitive layer and charging is carried out at an injection current which becomes saturated at said surface potential. According to this process, good images can be stably obtained irrespectively of environmental changes or even if the cycle number of the copying operation is increased.
