<p>Provided is an image formation device that can more precisely detect the relationships between actual amounts of color misalignment and predicted amounts of color misalignment. In addition to periodically determining that normal calibration needs to be performed, the provided image formation device forms color-misalignment detection marks when predicted amounts of color misalignment reach a threshold, then obtains the relationships between the predicted misalignments and misalignments between the actual image formation positions and a reference, and sets a misalignment prediction means accordingly.</p> |
