ABSTRACT:
A controlling section controls an image forming section to form a calibration pattern on an object. The calibration pattern includes a plurality of first patterns and a plurality of second patterns. Each of the first patterns includes at least one pair of marks. Each of the at least one pair of marks has different colors and overlaps with each other in a first direction. The first patterns have different degrees of overlapping from each other. Each of the second patterns is formed between one of the first patterns and another one of the first patterns in the moving direction. The detecting section detects the first and second patterns formed on the object. The correcting section corrects the image forming position in the first direction based on detection results of the first patterns, and corrects the image forming position in a second direction based on detection results of the second patterns.
