A liquid ejecting apparatus includes an ejection section that is configured to eject a droplet from a nozzle communicating with a pressure chamber by driving a drive element according to a supplied drive signal The drive signal includes a at least one ejection pulse including an ejection waveform element that changes an electrical potential to be ejected a droplet from the nozzle, and a residual vibration suppression element that changes an electrical potential to reduce the change in the pressure of the liquid in the pressure chamber, the change in the pressure remaining after the ejection of the droplet according to a natural vibration period of the ejection section. A weight of droplets to be continuously ejected from the nozzle when the drive signal is supplied to the drive element over a period corresponding to two or more drive periods is corrected by adjusting the residual vibration suppression element.
