摘要:
An element substrate capable of obtaining a high-quality printed image for a long period. The element substrate has a plurality of heaters, driving elements each of which is provided in correspondence with each of the plurality of heaters to selectively drive the plurality of heaters, an input terminal to receive a driving mode selection signal, and a block selection circuit which time-divisionally drives, in blocks of different timings, heaters in each of a plurality of groups each including a predetermined number of heaters and driving elements. The element substrate includes a logic circuit which time-divisionally drives the heaters in the group when the selection signal input from the input terminal is a signal for selecting a first driving mode, and simultaneously drives all heaters in the group when the selection signal is a signal for selecting a second driving mode.
