Abstract
The present invention provides an ink jet printing apparatus and an ink jet printing method which are capable of stabilizing the amount of ink ejection and of printing a high-definition image by selecting a driving condition with heat conductivity of an electrothermal converter being taken into consideration. The heat conductivity from a heater to ink is classified into heater ranks, and, on the basis of the heater rank, a voltage of a drive pulse to be applied to the heater is changed.
