1. An ink jet printing apparatus that prints an image by ejecting ink to a printing medium, comprising:
a printing head configured to include a printing element array in which a plurality of printing elements for generating thermal energy for ejecting ink are arranged in a predetermined direction; a scanning unit configured to cause the printing head to perform scanning for a unit region on the printing medium relatively in a cross direction which crosses the predetermined direction; a selection unit configured to select one of a plurality of printing modes which include at least a first printing mode in which printing is performed by driving a predetermined number of first printing elements among the plurality of printing elements arranged in the printing element array and not driving a predetermined number of second printing elements which are different from the predetermined number of first printing elements, and a second printing mode in which printing is performed by driving at least the predetermined number of first printing elements and the predetermined number of second printing elements; a first controller configured to perform control such that, with the scanning of the printing head by the scanning unit, printing is performed for the unit region in accordance with the printing mode which is selected by the selection unit; a first acquisition unit configured to acquire information regarding the number of driving times of the predetermined number of first printing elements in the printing by the first controller; and a second controller configured to perform, in a case where the first printing mode is selected by the selection unit, when ejection of ink by the first controller is not performed, control to drive the predetermined number of second printing elements, wherein the second controller drives the predetermined number of second printing elements in such a manner that the number of driving times of the predetermined number of second printing elements in a case where the number of driving times indicated by the information acquired by the first acquisition unit is equal to a first number of times is greater than the number of driving times of the predetermined number of second printing elements in a case where the number of driving times indicated by the information acquired by the first acquisition unit is equal to a second number of times that is smaller than the first number of times. |
