Abstract

PURPOSE:To enable an always good image to be obtained, by rotating a rotary body for a given time length after completing image forming steps of a preset number in response to a detection signal from a jam detecting means. CONSTITUTION:When jam does not occur, each output of sequential controller 401 is generated in a predetermined time sequence, and output of inverter 407 is zero and does not display jam. When jam occurs during copying, a jam signal is set to output D, jam is displayed through inverters 406, 407, and at the same time, zero is transmitted to the input of AND gate 403, resulting in stopping operation of a corona charger for destaticization before transfer. Since input of timer 405 changes 1-0, timer 45 starts action, and after a given time it changes its output to zero. This signal is delivered to AND gates 402, 404, and operation of an exposure lamp, a main motor, and a secondary corona charger are stopped.
