An acquisition means for acquiring a reference signal sequentially output according to the conveyance of the medium, and when each block obtained by dividing the plurality of recording elements into a plurality of predetermined number of blocks is sequentially driven at a predetermined interval Time-division driving means for repeatedly performing division driving; drive control means for generating timing signals corresponding to the drive timings of the plurality of blocks for driving each block in accordance with the reference signal acquired by the acquisition means; The drive control means has a first reference corresponding to a start timing of the time-division drive acquired by the acquisition means. The time interval between the second reference signal corresponding to the start timing of the next time-division drive and the second reference signal is the time for driving the recording elements of the predetermined number of blocks at the predetermined interval by the time-division drive means If the time is shorter, the second reference signal and the third reference signal corresponding to the start timing of the time-division drive that is further subsequent to the start timing of the time-division drive based on the second reference signal. The timing signal is generated so that the drive interval of each block when driving the plurality of blocks is shorter than the predetermined interval.
