An ink-jet recording apparatus of the present invention includes one or more ink-jet heads, a drive waveform generation circuit, a plurality of drive waveform selection circuits, and a plurality of drive signal generation circuits. The drive waveform generation circuit generates m different drive waveforms (m is equal to or greater than three). The drive waveform selection circuit selects n drive waveforms (n is smaller than m, and equal to or greater than two) from the m drive waveforms. The drive signal generation circuit selects in every predetermined recording cycle one drive waveform for one nozzle from the n drive waveforms selected by the drive waveform selection circuit, and generates a drive signal based on the drive waveform thus selected. At least one of the n drive waveforms selected by any one of the plurality of drive waveform selection circuits is the same as the drive waveform selected by another one of the drive waveform selection circuits.
