When the head temperature Tfinish, which is the head temperature at the time of completion of a preceding scan, is higher than the stable ejection temperature Tstable, the target temperature is made a temperature that is only a temperature value ΔT lower than the head temperature Tfinish. On the other hand, when Tfinish, the head temperature at the time of print completion, is lower than the stable ejection temperature Tstable, the target temperature is made a temperature that is only a temperature value ΔT higher than the head temperature Tfinish. Because of this it is possible to inhibit head temperature rise in the case where an image with a high print density is printed.
An ink jet printing apparatus that scans a print head, provided with a plurality of ejection openings for ejecting ink, and performs printing on a print medium, said apparatus comprising:
