An inkjet printing apparatus prints by ejecting ink on the basis of image data while scanning a printing head, in which ejection openings for ejecting the ink are arranged, over a printing medium in a direction different from a direction of the arrangement of the ejection openings. The inkjet printing apparatus includes a counting unit for counting the number of ink ejections in a predetermined area among a plurality of areas on the basis of image data for each of the plurality of areas, with the plurality of areas being obtained by dividing, in a main scanning direction, a region over which the printing head scans, and a correction unit for correcting the image data included in the plurality of areas on the basis of the number of ink ejections in each of the plurality of areas. In addition, a printing unit prints by driving the printing head on the basis of the corrected image data. The correction unit corrects image data included in a predetermined area on the basis of an added-up value of the number of ink ejections from an area corresponding to a position where the printing head scans, and printing is implemented to the corresponding predetermined area in the scan direction.
