In an ink droplet ejecting method and apparatus, a main driving waveform for the ejection of ink droplet is followed by two additional non-jet pulses, for one dot, without changing a driving voltage, whereby not only an ink droplet of a small volume can be obtained, but also the ink droplet speed in the second ejection after a stop which follows continuous droplet ejection is prevented from becoming lower. The application of a jet pulse signal A of one dot is followed by the application of both a droplet downsizing pulse B as a non-jet pulse for reducing the size of an ejected ink droplet, the pulse B being smaller in pulse width than the jet pulse signal A, and a jet stabilizing pulse C as a non-jet pulse for stabilizing the ejection of ink droplet. By so doing, even when the ink viscosity is low at a high temperature, the ejection of ink droplet is stabilized and a decrease in the droplet speed is prevented.
