Abstract
An image recording apparatus that includes a recording head controller that transfers image data and a driving waveform to a recording head in conjunction with position information of the recording head. The recording head controller includes a driving waveform storage unit that stores multiple driving waveform data, a number of driven nozzles calculator that calculates the number of nozzles driven simultaneously from the image data, and a driving waveform selector that selects one driving waveform data from the multiple driving waveform data based on the calculated number of driven nozzles and a predetermined threshold value of the number of driven nozzles.
