Abstract
An image forming apparatus includes a controller for forming an adjustment toner image in a region corresponding to between a first region corresponding to a preceding sheet and a second region corresponding to a subsequent sheet, wherein the controller selectively executes a first mode for setting as a first length a gap between the adjustment image and a trailing edge of the first region and for setting as a second length a gap between the adjustment toner image and a leading end of the second region, or a second mode for setting as a third length a gap between the adjustment toner image and the trailing edge of the first region and for setting as a fourth length a gap between the adjustment image and the leading end of the second region. The third is shorter than the first, and the fourth length is longer than the first length.
