Method electrophotographic printing
摘要:
A method of electrophotographic printing is disclosed. A recording medium comprising a photoconductive member and photo-modulation member laminated to each other, both exhibiting a photoelectric effect and a sensitized member made of a chargeable photoconductive member are arranged so as to face each other. A first electro-magnetic radiation beam (abbreviated in a beam hereinafter) which is intensity-modulated with data to be recorded is radiated to the recording medium at the photoconductive member side thereof to record the data to the photo-modulation member with the photoelectric effect. A second beam of constant intensity is radiated to the recording medium to emit therefrom a third beam exhibiting intensity variation subjected to the recorded data. The sensitized member is exposed with the third beam to form thereon a charge image corresponding to the recorded data. Toner is stacked onto the sensitized member formed with the charge image to form thereon a toner image. The toner image is then transferred onto a printing paper, thus to perform repeated printing utilizing the data once recorded to the recording medium.
