Patent attributes
An image forming apparatus includes an image forming unit, first and second detectors, and a corrector. The image forming unit includes first and second image forming units disposed downstream of the first unit in a transport direction of a recording medium and causes the first and second units to form predetermined correction images onto the recording medium. The first detector is disposed downstream of the first unit and upstream of the second unit in the transport direction, and detects the correction image formed by the first unit. The second detector is disposed downstream of the second unit in the transport direction and detects the correction image formed by the second unit. The corrector corrects an image position of the second unit in a width direction of the recording medium by using the correction images formed by the first and second units and detected by the first and second detectors.
