- the vibration generating unit by generating vibrations in the main scanning direction component from the vibration generating unit, the landing positions of the ink droplets ejected from the ink jet head are shifted unevenly as a whole in the main scanning direction. For this reason, when an image is printed on a medium in the same pass, the dot interval of the ink droplets in the joint of the print image in the same pass can be made non-uniform, and thus occurs in the joint of the print image in the same pass. Linear joint unevenness can be reduced.
