Abstract
A color image forming apparatus includes a carrier belt which runs along a transport path of a recording medium to transport the recording medium. A number of image-forming sections are aligned in the transport path. Each of the plurality of image-forming sections forms a toner image of a corresponding color included in an image signal. A plurality of transfer units are provided, with each being disposed to oppose a corresponding one of the number of image-forming sections. Each of the number of transfer units transferring the toner image of the corresponding color to the recording medium. A fixing unit is provided that fixes the toner image to the recording medium. A controller is provided that detects a number of colors in the image signal. The controller sets one set of speeds from a plurality of different sets of speeds in accordance with the number of colors. Each set of speeds includes a speed of the carrier belt, a speed at which each of the image-forming sections forms a respective toner image of a corresponding color, and a speed of the fixing unit. The speed of the carrier belt, the speed at which each of the image-forming sections forms a respective toner image of a corresponding color, and the speed of the fixing unit of any one respective set of speeds are substantially equal to each other.
