Abstract
An image forming apparatus that forms an output image including an authentication image for authenticity determination on a medium. The image forming apparatus includes: a recording head configured to discharge a droplet onto the medium; a drive unit configured to perform main scanning in which the recording head moves in a main scanning direction and sub scanning in which the medium is fed in a feeding direction; and a control unit configured to control, based on image formation data representing the output image, the main scanning and the sub scanning performed by the drive unit, and the discharge of the droplet performed by the recording head. The control unit performs a control to form the authentication image by a plurality of times of the main scanning in which feeding positions of the medium in the feeding direction are different, and performs a control so that at least one feeding amount of the medium in one sub scanning is different between a feeding amount at time of forming the authentication image and a feeding amount at time of forming a portion of the output image that does not include the authentication image.
