Patent ID: 8474941

Claim:
An inkjet printing apparatus to print an image on a printing medium comprising: a print head capable of ejecting ink from a plurality of ejection ports based on print data, the plurality of ejection ports including a plurality of first ejection ports providing a first ejection volume of ink and a plurality of second ejection ports providing a second ejection volume of ink, the second ejection volume being smaller than the first ejection volume; a temperature detecting unit that detects a temperature of the print head; a heating unit that heats the print head so that the temperature detected by the temperature detecting unit reaches a target temperature; and a heating control unit that sets the target temperature; wherein the heating control unit sets the target temperature in consonance with an increase in a total value obtained by adding a first ejection number of ink to be ejected from the first ejection ports to a value obtained by multiplying a predetermined coefficient by a second ejection number of ink to be ejected from the second ejection ports.
