An image forming apparatus includes a mounting table on which an object whose image is to be scanned is mounted; an image forming section that forms an image, which includes a first image for measuring a relative position with respect to an end portion of a paper, on a first side of the paper; an image scanning section that scans the image mounted on the mounting table; and a position correction section that corrects a relative position of an image, which is formed on the paper, with respect to the paper based on a result of scanning performed by the image scanning section, in which in a case where the image scanning section scans the end portion of the paper and the image formed on the first side of the paper in a state in which the first side of the paper on which the first image is formed faces the mounting table, the end portion of the paper is mounted on the mounting table at a position separated from an end portion of the mounting table, and, further, the paper is covered with a cover paper, and the image forming section forms, on the first side of the paper, a third image that uses, as an alignment object, a second image for alignment formed on a side of the cover paper opposite to a side on which the cover paper is in contact with the paper while a part of the paper is mounted in a state of protruding from the mounting table and a first edge of the cover paper.
