Abstract
A patch-pattern forming unit causes an image forming unit to form a patch pattern including a plurality of patches on a conveying member. A detecting unit detects the patch pattern formed on the conveying member. An adjusting unit adjusts an image forming condition of the image forming unit based on a result of detection by the detecting unit. The patch pattern has a length substantially equal to a distance between a patch-pattern start position, which is located at a space corresponding to at least a predetermined margin of a recording medium from a position of the image, and a position of the detecting unit.
