Abstract
PURPOSE:To eliminate the bad influence generated by overrun due to inertia of the photorsensitive drum, by delaying power break of the destaticizer more than power break of the main motor by a fixed time when the turn-off command of the main motor is issued. CONSTITUTION:A delay element is given to the control system which switches power supply for destaticizer 7, transfer equipment 5, and separator 8 according to turn-on and off commands of the main motor. When the turn-off command is issued, power break of each charge part is delayed more than power break of the main motor by a fixed time to destaticize even for rotation of photosensitive drum 1 due to inertia, and the control is performed to prevent the photosensitive drum 1 from passing under destaticizer 7 with the surface potential plus-charged. A delay element is given to the control system for the main motor; and when the turn-on command is issued, photosensitive drum 1 is driven at a fixed time after power supply to respective charge parts such as destaticizer 7.
