In a liquid-ejecting method for ejecting liquid contained in a liquid chamber from a nozzle as a liquid droplet group, the ejection amount of each liquid droplet of the continuously ejected liquid-droplet group can be stabilized corresponding to a wide frequency band of a pulse signal. Also, when one pixel is formed with a plurality of liquid droplets using a head capable of deflecting the ejecting direction of the liquid droplet, the image quality is improved by reducing the landing positional displacement between plural liquid droplets for forming the one pixel.
