PROBLEM TO BE SOLVED: To provide an inkjet recording apparatus capable of discharging dots having different sizes in each 1 pixel cycle by a simple driving circuit configuration without unnecessarily elongating a driving cycle.SOLUTION: A driving waveform has a first driving waveform (PLSTM1) formed of a non-GND waveform, a second driving waveform (PLSTM2) formed of a non-GND waveform different from the first driving waveform, and a third driving waveform (PLSTM0) formed of a GND waveform, and a driving voltage V1 of the first driving waveform and a driving voltage V2 of the second driving waveform is |V1|>|V2|. A driving circuit selects at least the first driving waveform and the second driving waveform or only the first driving waveform at each predetermined time in one pixel cycle in accordance with the discharge data, applies this to one of two driving electrodes of a pressure generating means and also applies only the second driving waveform to the other to operate the pressure generating means by a differential waveform between the two driving electrodes. |
