Abstract
PURPOSE: To achieve function expansion by simultaneously exposing both negative and positive images on one photoreceptor and developing these by the same polarity toner.
CONSTITUTION: The 1st, 2nd corona dischargers 17, 16, exposure device 2, microfilm mounting device 15, printer 10, etc. are disposed around a photosensitive drum 1. As a result of this, if negative and positive charges are subsequently applied to the photosensitive drum 1 surface by the 1st, 2nd corona dischargers 17, 16 and the recording light image is radiated to the printer 10 followed by full-surface exposure with the exposure device 2 snd developing with the toner of the developing device 9, then the copying of printing becomes possible and if the image of an original 4 is exposed by the exposure device 2 after subsequent application of negative and positive charges by the 1st, 2nd corona dischargers 17, 16, then the copying of the original 4 becomes feasible. Further if the microfilm mounted to the microfilm mounting device 15 is exposed while operating the 2nd corona discharger 16 after application of negative charge by the 1st corona discharger 17 followed by full-surface exposure by the exposure device 2, then the copying of the microfilm becomes feasible.
