Abstract
In a configuration in which a printhead including a plurality of first printing elements for discharging ink droplets and a plurality of second printing elements for discharging ink droplets larger than ink droplets discharged by the first printing elements is used, the first and second plurality of printing elements are divided into multiple blocks in such a manner that the first printing elements belong to one block and the second printing elements belong to another block. The blocks are individually driven in a time-divisional manner. In the time-divisional driving, the block consisting of the plurality of first printing elements is driven first and then the block consisting of the second printing elements is driven.
