<p>Movement between ink ejection targets is carried out in a short time when an ejection head moves in a main scanning direction by reversing. An ink ejector in which a main scanning direction moving time when an ink ejecting means moves between positive direction ejection targets (2a)(2c) is longer than a sub-scanning direction moving time, a main scanning direction moving time when the ink ejecting means moves between negative direction ejection targets (2b) is longer than a sub-scanning direction moving time, a sub-scanning direction moving time required for the ink ejecting means to move from the final positive direction ejection target, which the ink ejecting means scans last, out of the plurality of positive direction ejection targets (2a) to the initial negative direction ejection target, which the ink ejecting means scans first, out of the plurality of negative direction ejection targets is longer than a main scanning direction moving time, and the ink ejecting means starts a sub-scanning direction movement moving to the initial negative direction ejection target when it starts movement from the final positive direction ejection target to the initial negative direction ejection target.</p> |
