Abstract:
1. An apparatus forming an image on a recording medium, the apparatus comprising: a conveying unit conveying the recording medium; a driving unit driving the conveying unit; a first calculation unit calculating a correction value based on a position error of the recording medium with respect to the image; a detection unit detecting a current conveying speed of the recording medium being conveyed by the conveying unit; a position controller to which the current conveying speed detected by the detecting unit, one of a predetermined first target conveying speed and a target position of the recording medium, and the correction value calculated by the first calculation unit are input, and that outputs a second target conveying speed; a second calculation unit to which a value based on the second target conveying speed, the current conveying speed detected by the detection unit, and one of the predetermined first target conveying speed and a speed based on the target position of the recording medium, are input and that calculates a speed error; and a speed controller controlling the driving unit based on the speed error calculated by the second calculation unit.
