Abstract
A head driving device drives a liquid ejection head. The liquid ejection head includes a plurality of nozzles and a plurality of pressure generating devices provided respectively corresponding to the nozzles. The head driving device includes a driving-waveform correcting unit configured to correct driving waveform data that defines ejection characteristics of liquid to be ejected from the nozzle based on interference patterns expressing variations in the ejection characteristics caused by an interference occurring in the nozzle.
