An image forming apparatus includes: an image forming unit that includes a developing unit with a developing roller to form an image using toner; a controller; and a detection unit that detects a plurality of toner patches formed at different densities on an image carrier by the image forming unit. The controller controls the image forming unit to form the toner patches on the image carrier so that each interval between the toner patches is equal to or greater than a length corresponding to a circumference length of the developing roller.
