With an ink jet head in which color nozzles are aligned with an interval of three times an interval of black nozzles at the right side in a scanning direction of the black nozzles, when an image is recorded by ejecting black ink and color ink superposed on each other, a first unit recording operation is repeatedly executed, in which scanning by ejecting ink from at least one of the black nozzles and color nozzles is repeated three times while moving a carriage in the scanning direction, and a recording sheet is conveyed by a predetermined amount every time scanning is completed. In the first unit recording operation, the carriage is moved to the left side while ink is ejected from both the black nozzles and color nozzles at the first scanning. Moreover, in each of the second and third scanning operations, ink is ejected only from the color nozzles.
