Abstract
A correction information creation device including: a recording head; a rotating body; a first detector that detects a period of a pulse signal generated in accordance with rotation of the rotating body; a first calculation section that calculates a period of a clock signal; a second detector that detects a space between corrective images that are formed synchronously with a period of the clock signal, while the rotating body is being rotated at a predetermined rotation speed, by two sets of image formation elements of the recording head; a second calculation section that calculates a distance between a measurement position of a peripheral surface of the rotating body and the axial center of the rotating body; and a memory that stores the calculated distance to serve as information for correcting the period of the clock signal.
