<P>PROBLEM TO BE SOLVED: To improve the quality of an image formed by a liquid ejecting apparatus capable of performing a bidirectional printing. Ž<P>SOLUTION: A raster (POL raster) formed by a partial overlap (POL) is formed such that pixels (first type of dots) formed upon a going movement and pixels (second type of dots) formed upon a coming movement are alternately arranged. The first type of dots and the second type of dots can be alternately formed, for example, by controlling an amount of transport of a print sheet and an amount of feed in a horizontal direction (main scanning direction) of a recording head. In such a way, it is possible to alternately form the dots formed in opposing filling directions in the POL raster. By changing the allocation of POL nozzles in an odd-numbered pass and an even-numbered pass and performing an anomalous feeding process of the print sheet, it is possible to change a combination of the POL nozzles forming the POL raster. Accordingly, since a noise occurring in the main scanning direction of an image printed on the print sheet can be restrained, it is possible to improve the quality of an image.
