Abstract: An image forming apparatus includes an image forming unit, a transfer unit, and a controller. The transfer unit transfers a developer image formed by the image forming unit onto a transfer object. The controller controls each of the image forming unit and the transfer unit on a basis of printing data. The controller performs a printing control to cause a first printing operation and a second printing operation to be executed. The first printing operation forms a first developer image directed to an entire pixel region of a print image and transfers the first developer image onto the transfer object. The second printing operation forms a second developer image directed selectively to a high-gradation pixel region and transfers the second developer image onto the transfer object. The high-gradation pixel region is a pixel region, having a gradation value equal to or greater than a threshold, of the print image.
