Abstract:
An element substrate according to an embodiment of the present invention includes a plurality of print elements and a plurality of drive elements for driving the plurality of print elements. The element substrate comprises a generation circuit configured to generate a first drive signal that drives drive elements belonging to a first group among the plurality of drive elements, and a second drive signal that drives drive elements belonging to a second group among the plurality of drive elements, using a selector configured to switch a signal transmitted from outside of the element substrate and an output destination of the signal within one block period in driving the plurality of drive elements by dividing the plurality of elements into the plurality of blocks. The first drive signal and the second drive signal are generated at different timings.
