ABSTRACT:
An element substrate for a recording head includes groups of heating resistors that are disposed next to one another in each group; logic circuits configured to time-divisionally drive the heating resistors in units of one block; a heat enable signal line common to the groups of heating resisters, the heat enable signal line supplying a heat enable signal to each of the groups of heating resisters; and delay circuits connected to the heat enable signal line at positions between the groups of heating resisters. A signal output from each delay circuit to the next group is inverted.
