Abstract
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.
