Abstract
A liquid ejecting apparatus includes a liquid ejection head, a circulation control section that controls a circulation operation of circulating the liquid in the first individual flow path, and a minute vibration control section that supplies a drive signal having a first waveform to the first piezoelectric element so as to control a minute vibration operation of causing the liquid in the first nozzle to vibrate to such a degree that the liquid is not ejected from the first nozzle. The circulation control section starts the circulation operation at a first time, and the minute vibration control section starts the minute vibration operation at a second time earlier than the first time.
