In an inkjet printing apparatus comprising a printhead having a plurality of nozzle arrays, where a plurality of nozzles for one ink are arranged in a predetermined direction, for performing printing by moving the printhead relatively to a printing medium in a direction crossing to the predetermined direction, the plurality of nozzle arrays are controlled so that a printing duty of preceding nozzle arrays in the relative movement is higher than a printing duty of subsequent nozzle arrays. By virtue of this control, it is possible to suppress generation of color mixture and bleeding, and achieve high-speed printing with high image quality.
