摘要:
An element substrate has a plurality of printing elements, and a block selection unit which divides the plurality of printing elements into a plurality of blocks and time-divisionally drives the blocks. The element substrate includes a plurality of input terminals which divide the plurality of printing elements included in each block into a plurality of groups and supply a driving voltage to the printing elements belonging to each group, a delay circuit which externally receives an enable signal for enabling energization to the printing elements and generates a plurality of delayed enable signals having different delay times with respect to the enable signal, and a wiring which supplies the enable signal and the plurality of delayed enable signals output from the delay circuit to different groups in the order of the different delay times.
