Abstract
An image forming apparatus includes a head; a scanning section; and a transport section. A first region is formed in the head between a nozzle formed at a first end and a first nozzle that is a first predetermined distance away, in the sub-scanning direction, from the nozzle formed at the first end. A second region is formed in the head between a nozzle formed at a second end and a second nozzle that is a second predetermined distance away, in the sub-scanning direction, from the nozzle formed at the second end. When the head, the scanning section, and the transport section form an image on the medium, a moving-average nozzle usage ratio within a region between the first region and the second region changes at a lower rate than moving-average nozzle usage ratios within the first region and the second region.
