Abstract

PURPOSE:To improve separation probability by changing the intensity of destaticizing by a corona generator according to the potential or toner pickup of the ground part of photoreceptor at the time of separating transfer paper from the photoreceptor surface by separating coronas. CONSTITUTION:As the ground potential increased, the DC bias voltage of a separating charger is incrased. Namely, the DC bias is changed in cooperation with the aperture value of exposure optical system or part of exposure rays is received with a photo detector and the DC bias is changed by the change in its photoelectric conversion output. Or the DC bias of the separating charger is changed by the pick up of the torner on photoreceptor ground part. Namely, the intensity of destaticizing of separating coronas is changed over in cooperation with changing over of the developing bias.
