Abstract
PURPOSE:To prevent action of corona destaticization on areas except as image forming area from being effected alone, to prevent carrier attachment onto a photoreceptor, and to form a high quality image, by according actuating timings of charging and destaticizing on the photoreceptor. CONSTITUTION:Heating of a couple of rollers 13 to fixable temperture with apparatus 18 enables copying operation, and start of rotation of photosensitive drum 1 actuates corona destaticizer 26 and corona charger 2. The timing of operation start of charger 2 is set to t1 seconds later than the start of destaticizer 26 so as to accord destaticizing of part of the drum 1 surface by destaticizer 26 with charging of part of the surface by charger 2. Uniformly charged drum 1 is imagewise exposed by a slit exposure system to form a static latent image corresponding to an original, and this image is developed by developing apparatus 3.
