Abstract
PURPOSE:To obtain the stable images of good quality without intricating constitution by controlling the quantity of light from a light source thereby performing the residual image removal of a rotator and substantial uniformalization of its potential. CONSTITUTION:When a copying switch is turned on, a predestaticizing charger 24, a lamp 3, primary-, secondary- and transfer chargers 5, 6, 9 and a shutter 25 go on. Pre-coronas, primary-, secondary- and transfer coronas, blank exposure and uniform exposure are applied to the photoreceptor of a rotating drum 2 to clean the remained toner, charge, memory etc. respectively, whereby the preparation for starting copying is made. At this time, the lamp 3 is weak lighting. As the drum makes predetermined rotation, the platen 1 also moves and the lamp 3 emits light strongly, then the shutter 25 is turned off to stop blank exposure which is then changed to image exposure. The blank exposure is performed in order to prevent the occurrence of potential unevenness. Thereby, the always stable transfer images of good quality may be obtained.
