Abstract
An embodiment of the present invention provides an ink jet printing apparatus including: a print head including a printing element array provided with printing elements each configured to generate thermal energy required to eject an ink, a supply flow channel provided along the printing element array and configured to supply the ink to the respective printing elements, an opening provided to the supply flow channel and configured to cause the ink to flow in, and heating units provided along the supply flow channel and configured to heat the ink inside the supply flow channel; and a heating control unit configured to carry out heating control of the heating units based on a heating pattern determined based on heating intensity distribution, the heating intensity distribution representing heating intensities corresponding to the respective heating units and representing the heating intensities corresponding to positions in a direction of the printing element array.
