PROBLEM TO BE SOLVED: To improve a variation in ink ejection volume by smooth correction of high resolution. SOLUTION: A reference signal output part outputs a reference signal having a reference pulse waveform of a drive pulse signal for operating a drive element. A correction data storage part stores correction data respectively calculated for each of a plurality of nozzles. A drive signal generation part generates a drive pulse signal applied to each of the drive elements respectively corresponding to the plurality of nozzles by correcting the reference pulse waveform of the reference signal with correction data stored in the correction data storage part for the nozzle corresponding to the drive element.
