Abstract
A simpler method is used to correct the tilt of the reading device. [Solution] The image forming apparatus transports a sheet in a predetermined transport direction and forms an image on the sheet. The image forming apparatus forms a first test image on the sheet and causes the reading means to read the first test image from the sheet. Based on the reading result of the first test image, the image forming apparatus corrects the tilt of the reading means relative to the transport means.
