ABSTRACT:
A fourth-unit tandem type color copier includes four photosensitive drums, a conveyor belt running, in a predetermined direction, in rolling contact with the respective drums, drum motors driving the corresponding drums, and a belt motor running the conveyor belt. Currents driving the drum motors and belt motor are so supplied as to be gradually stepped up from the starting of these motors and it is possible to lower a burden on a power source caused when the respective motors are started.
