ABSTRACT:
An image forming apparatus includes an image forming section, a controlling section, a detecting section, and a correcting section. The image forming section forms an image on an object. The controlling section controls the image forming section to form a calibration pattern on the object. The calibration pattern includes a plurality of marks in a first group and a plurality of marks in a second group. The plurality of marks in each of the first group and the second group is arranged in a first direction over a predetermined range. The plurality of marks in each of the first group and the second group includes first marks and second marks. The first mark in the first group corresponds to the second mark in the second group in a second direction different from the first direction in at least part of the predetermined range. The first mark in the second group corresponds to the second mark in the first group in the second direction in at least part of the predetermined range. The detecting section detects the first mark and the second mark formed on the object. The correcting section corrects, based on the detected first mark, a deviation in the first direction of an image forming position at which the image forming section forms an image, and corrects, based on the detected second mark, a deviation in the second direction of the image forming position.
