ABSTRACT:
The electrophotographic process of this invention is characterized in that a single layer organic photosensitive material having an absorbance, at a maximum absorption wavelength of a visible portion per .mu.m of the thickness of a photosensitive layer, of at least 0.05 is used, and for its charge elimination, a light-emitting diode light which emits a light of a maximum absorption wavelength or a light in its vicinity is irradiated. According to this process, when image formation carried out repeatedly a number of times, a decrease in an early period surface potential can be effectively prevented and a brilliant image can be formed in a high concentration.
