Abstract
An image forming apparatus including: (a) a feed mechanism including a motor and a feeder moved by the motor for feeding a medium; (b) a recording head for ejecting an ink toward the medium to form an image; (c) a feed controller for controlling the motor so as to move the feeder to a target operating position that causes the medium to be positioned in a desired position; and (d) an ink ejection controller for causing ink ejection portions of the recording head to eject the ink toward the medium. The feed controller includes: a target-operating-position changer for changing the target operating position as an original target operating position to a modified target operating position in which influence of a cyclic variation of an operation velocity of the feeder is smaller than in the original target operating position. The ink ejection controller includes: an ink-ejection portion shifter for shifting the ink ejection portions in upstream or downstream direction in which the desired position is shifted as a result of change of the target operating position.
