ABSTRACT:
An image forming apparatus includes: an image formation control unit for forming print images on an image carrier and for forming a reference toner pattern having a predetermined size between the print images formed on the image carrier; a reference image density detecting unit for detecting a image density of the reference toner pattern; and an image forming condition adjusting unit for adjusting an image forming condition based on the image density detected by the reference image density detecting unit. If a toner amount of one or plurality of the print images is greater than a predetermined value, the image formation control unit prevents any further adjustment operation performed by the image forming condition adjusting unit.
