An electrophotographic process includes performing removal of electricity or pre-charging by direct current corona discharge and main charging by direct current corona discharge of a polarity reverse to the polarity for removal of electric charge or pre-charging on an organic photoconductive photosensitive layer chargeable at both the positive and negative polarities. Then is performed imagewise exposure, development with a toner and transfer of the toner image. Such operations are repeated to form plural images. Main charging is carried out with an applied current such that the photosensitive layer surface potential is saturated at 500 to 700 volts (absolute value) and removal of electric charge or pre-charging is carried out with at an applied current lower than the saturation injected current value and corresponding to 40 to 90% thereof. |
