ABSTRACT:
A copier includes one motor for driving a photoconductive element unit, a developing unit, a fixing unit and other units, and another motor for driving an optical system. A clutch is interposed between the various units and the motor adapted to drive them. A device is provided for uncoupling the clutch for a predetermined period of time to interrupt the transmission of a drive force to the various units. The motor assigned to the units, clutch and drive force interrupting device are controlled such that the drive force interrupting device maintains the clutch uncoupled until the motor reaches a predetermined synchronous rotation speed after the start of rotation so as to interrupt the transmission of the drive force to the load, the clutch being coupled upon the lapse of the predetermined period of time to drive the load.
