Abstract:
An ink-jet recording apparatus comprising:a plurality of nozzles for firing ink drops;a plurality of pressure-application ink chambers, communicating with said plurality of nozzles, respectively;a plurality of energy generating elements for generating energy for applying pressure to ink in the plurality of pressure-application ink chambers that fires the ink drops from said plurality of nozzles, respectively;driving-waveform generating means for generating a plurality of different driving waveforms for driving said plurality of energy generating elements, wherein each of the plurality of driving waveforms has a maximum driving voltage and a rise time and wherein the higher the maximum driving voltage the longer the rise time; anddriving-waveform selecting means for selecting one of the plurality of driving waveforms generated by said driving-waveform generating means for each one of said plurality of energy generating elements in accordance with image information.
