ABSTRACT:
In an image forming apparatus, a plurality of image forming means devices are sequentially arranged along a conveyor belt and sequentially form register marks on the conveyor belt. A sensor senses the register mark formed by the individual image forming device. A correcting section corrects, based on the output of the sensor, the register position of the individual image forming device with respect to a regular deviation component and an irregular deviation component fluctuating at a particular period. The apparatus is capable of producing high quality color images suffering from a minimum of color misregister.
