Abstract
A recording apparatus uses a liquid recording head for effecting recording by ejecting liquid through ejection outlets corresponding to heat generation elements provided in the recording head. The recording head has a heating device for heating the recording head. A controller will select a heat generating element from among the heat generating elements to correct a temperature distribution of the recording head resulting from the heating by the heating device such that the heat generating element generates heat to such an extent that liquid for recording is not ejected through the ejection outlet during the temperature correction.
