    Abstract: The object of the present invention is to provide an ink jet printing apparatus which can realize both a high speed printing and a high quality printing without color deviations when each of the print areas is printed in a plurality of scans by a plurality of print heads ejecting different kinds of ink. For this purse, this invention has a controller (100) for controlling for each print head (1) independently widths and positions of active nozzle groups in the print heads (1), the active nozzle groups representing those of the plurality of nozzles in the print heads (1) which are used for printing, wherein the controller (100) controls the widths and positions of the active nozzle groups according to a set printing condition.

    Abstract: An ink jet recording apparatus including a recording head for performing print recording by ejecting ink from an ejection orifice by thermal energy; temperature sensors provided in the recording head; a temperature calculation means for calculating a temperature change of the recording head in a unit time as a discrete value on the basis of the supply of energy input to the recording head, and for calculating the temperature change of the recording head by accumulating the discrete value in the unit time; a temperature presuming means for presuming a head temperature by both a calculated value of the temperature change and an adopted base value of the head temperature; a detection means for detecting a difference between the head presumed temperature and a detected temperature sensed by the temperature sensors; an update means for updating the adopted base value of the head temperature by the difference; and a control means for controlling ejection of the ink to be stabilized in accordance with the head presumed temperature.
