An ink jet printing apparatus and a print head recovery method are provided which effectively execute a preliminary ejection to eject ink not contributing to image printing from nozzle opening of the print head to maintain the ink ejection performance in good condition. The ink in the print head is heated to a first temperature, at which a first preliminary ejection is executed. Then, when the ink temperature falls to a second temperature, which is lower than the first temperature, a second preliminary ejection is executed.
