Original Abstract Submitted

An image-forming apparatus includes image-forming units configured to respectively form images of different colors; an interface for use in instructing the image-forming units to form a test image; and a controller configured to: control the image-forming units to form a first test image including image regions of the colors, the first test image being used for correcting density unevenness in a first direction; and control the image-forming units to form a second test image including image regions of the colors, the second test image being used for correcting density unevenness in a second direction. In a case where the interface receives an instruction to form both of the first test image and the second test image, the controller is configured to control the image-forming units to form the first test image and then form the second test image.
