ABSTRACT:
In the present apparatus, nozzle openings of a pair of adjacent nozzle rows among a plurality of nozzle rows are shifted relative to each other with respect to a direction in which the nozzle rows extend. Liquid of the lightest color is supplied to the nozzle row nearest to an end of a liquid ejecting head with respect to a direction perpendicular to a direction in which the nozzle rows extend, and liquid of the darkest color is supplied to the nozzle row at a middle part of the liquid ejecting head with respect to the direction in which the nozzle rows extend. A controller controls the liquid ejecting head to eject liquids through the nozzle openings of all the plurality of nozzle rows of the liquid ejecting head while the liquid ejecting head is moving for forward and backward scanning strokes. The deterioration of image quality and the increase of approach regions due to the increase of the length of the liquid ejecting head can be prevented.
