Provided is a driving circuit for an inkjet recording head, the inkjet
recording head having plural pressure generation chambers filled with
ink, a nozzle, and a vibration generation section which causes a pressure
change in each pressure generation chamber. The driving circuit includes:
a driving waveform generation section including first and second waveform
generation sections that generate respectively different driving
waveforms during one driving cycle on the basis of sizes of ink droplets;
a control section that outputs a waveform select signal; and a driving
waveform supply section that supplies a driving waveform selected based
on the waveform select signal to the vibration generation section. When
the selected driving waveform is generated by the first waveform
generation section, the driving waveform is selected during each of
periods into which the driving cycle is divided, and is supplied to the
vibration generation section.
