There is provided an image recording apparatus including an image recording head; a scanner; a conveyer; and a controller. The controller is configured to execute first and second recording modes in which the controller causes the image recording head to accelerate to first and second velocities, to move at the first and second velocities, and then to decelerate from the first and second velocities, while causing the image recording head to record the image at least during moving at the first and second velocities, respectively. In a case that the controller has determined, based on printing data, that the image is to be recorded during a first velocity changing period, the controller executes the second recording mode. The first velocity changing period includes a first acceleration and deceleration periods in which the image recording head accelerates and decelerates, respectively.
