A color copying machine includes a plurality of image forming sections having rotatable photoconductive drums, respectively. One of the drums, which is used for forming images in black, is rotated by a first drum drive motor, and the other drums are rotated by a second drum drive motor. A plurality of transfer devices are arranged to oppose the image carriers, respectively. A paper sheet is sequentially moved to positions opposing the drums and clamped between the drums and transfer rollers so as to transfer images on the drum to the paper sheet. When a ...
