Abstract
An image forming apparatus includes an image forming device, a corrector, and a controller. The image forming device is configured to form an image on a sheet using a rotating body under a predetermined image forming condition. The corrector is configured to correct the image forming condition to adjust image density unevenness corresponding to a rotation cycle of the rotating body. The controller is configured to control the image forming device to form on at least one sheet (i) plural test images that are different in correction amount for the image forming condition and (ii) pointing portions indicating intervals corresponding to the rotation cycle of the rotating body, in a state where the rotating body is continuously rotated.
