An object of the present invention is to provide an ink jet printing apparatus and an ink jet printing method which can prevent print quality from being degraded by a non-ejection nozzle while maintaining high-speed printing performance based on a raster division method. The present invention sequentially performs, array by array, an operation of ejecting ink through a plurality of nozzle arrays to sequentially print an image in a plurality of raster forming areas of a print medium. At this time, if an expected printing result fails to be achieved owing to a nozzle included in any of the nozzle arrays which exhibits degraded ejecting performance, degrading image quality, then the ejection order of the plurality of nozzle arrays is changed. This enables a reduction in the degradation of print quality caused by the ejecting performance of the nozzles.
