Abstract

An image forming apparatus includes an image bearer, a toner image forming unit, a detector, and a controller to adjust an image forming condition based on a detection result by the detector. During a non-printing period, multiple toner patterns are formed in an end and center portions of the image bearer in a direction perpendicular to a direction in which the image bearer moves, and a smaller number of toner patterns selected from the multiple toner patterns are formed in a non-image area, in the end portion of the image bearer, during a printing period. The controller determines a target density X of the smaller number of toner patterns by X=H (a mean detected density of the multiple toner patterns formed in the end portion)×J (a predetermined reference value)/I (a mean detected density of the multiple toner patterns formed in the end portion and in the center portion).
