Abstract
An image forming apparatus includes an image forming unit configured to form an image, a conveying unit configured to convey a sheet on which the image is formed, a reader configured to read the sheet conveyed by the conveying unit and a controller. The controller is configured to execute first calibration in which a density of an image to be formed by the image forming unit is controlled based on a result of reading by the reader, and execute second calibration in which a geometric characteristic of an image to be formed by the image forming unit is controlled based on a result of reading by the reader. The controller allows usage of a sheet of a first type in the first type of calibration, wherein the controller prevents usage of a sheet of a second type in the first type of calibration.
