An ink jet printing apparatus prevents deterioration of the printed image resulting from degradation of refilling characteristics caused by a rise of the printing head temperature as well as decrease in the printing speed. More particularly, the temperature of the ink ejecting head is measured so that the settings of a pulse width and a drive voltage of a drive pulse to be applied to an electro-thermal converting element are altered based on the measured temperature of the ink ejecting head in such a manner that the pulse width is shortened and the drive voltage is increased as the temperature of the ink ejecting head rises. |
