Title: Image forming device
Inventor: YOSHIDA TAKESHI
IPC: G03G21/00
Filed: 1989-07-18
Abstract: PURPOSE:To prevent toner from being consumed more than necessary and faulty cleaning from occurring by starting a pre-fatigue stage after the circumferential speed of a photosensitive body is stabilized. CONSTITUTION:When a copying button 2 is depressed in a state where an image processing action is not executed, a main motor 7 is started to be driven and the rotation of the photosensitive drum rises. A pulse generator 8 including a pulse plate and an optical sensor which converts the rotational amount of the pulse plate into an electrical pulse signal to transmit to a microcomputer 1 is connected to the main motor 7. The pre-fatigue stage is executed at the point of time when specified cyclic time is fully attained by increasing the speed of the motor 7, that is, when the circumferential speed of the surface of the photosensitive drum is made constant. Thus, higher potential than necessary is not formed on the surface of the photosensitive body at the pre-fatigue stage, thereby preventing the toner consumption from increasing and the faulty cleaning from occurring.
