Patent ID: 8210638

Claim:
An ink jet printing apparatus comprising: a print head provided with a plurality of chips, each chip includes a nozzle member provided with a plurality of nozzles for ejecting ink, the plurality of chips are arranged so as to be shifted in a direction in which the plurality of nozzles are arranged, and such that an area where a plurality of nozzles of a first nozzle member included in a first chip and an area where a plurality of nozzles of a second nozzle member included in a second chip overlap one another in a direction crossing the nozzle arranging direction; a moving unit configured to move the print head relative to a print medium; a printing unit configured to print an image on the print medium by causing the print head to eject the ink while the print head moves relative to the print medium; a detection unit that detects an inclination of the print head in a direction orthogonal to a direction in which the print head moves relative to the print medium; and a controller that controls an ink ejecting operation of the plurality of nozzles in the overlapping portions of the first chip and the second chip on the basis of the inclination of the print head in the direction orthogonal to the direction in which the print head moves relative to the print medium detected by the detection unit.
