Abstract: When a specified image is recorded while ranging over a boundary between a first dot recording range and a second dot recording range, a controller of an image recording apparatus judges whether or not a predetermined condition is fulfilled, the predetermined condition including at least one of a first condition which relates to a duty and a second condition which relates to a positional deviation in a scanning direction of a landing position of a liquid. If the predetermined condition is fulfilled, the dot belonging to a correcting portion is formed by correcting discharge in which the liquid in a discharge amount smaller than a set discharge amount is discharged. If the predetermined condition is not fulfilled, the dot belonging to the correcting portion is formed by ordinary discharge in which the liquid in the set discharge amount is discharged.
