The present invention provides an ink jet printing apparatus and an ink jet printing method in which even with a variation in ink ejection amount depending on an image print area, the ink ejection amount for preliminary ejection can be optimally set. For this purpose, a print area is divided into a plurality of areas, and the number of ink ejections through a nozzle is measured for each of the areas. Based on the number of ink ejections for each area, the number of ink ejections for the preliminary ejection is determined.
