Abstract
An image forming apparatus forms a multicolor toner image by superposing a plurality of monochromatic toner images on a transfer material. The apparatus has: a plurality of toner image carriers on which monochromatic toner images of different colors are respectively formed; toner-image-carrier driver for driving all the toner carriers to rotate in a predetermined period; and a position-shift correction quantity detector for determining the position shift quantity of each monochromatic toner image in the multicolor toner image and outputting a position-shift correction quantity corresponding to the detected result. The toner-image-carrier driver controls the period of rotational driving of each toner image carrier in conformity with the position-shift correction quantity.
