发明名称 Image forming apparatus, image forming method, and storage medium
摘要 An apparatus for forming an image on a recording medium. The apparatus includes a conveying unit conveying the recording medium; a driving unit driving the conveying unit; a 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 calculating a second target conveying speed based on the correction value, the current conveying speed, and a first target conveying speed of the conveying unit or a target position of the recording medium; and a speed controller controlling the driving unit based on the second target conveying speed, the current conveying speed, and the first target conveying speed.

主权项 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.
