For forming one dot by jetting a plurality of ink droplets, a drive pulse signal in an ink-droplet jetting apparatus includes a first main pulse for jetting, a first regulating signal which is inserted at a first interval from the first main pulse, and a second regulating pulse which is inserted at a second interval from the first main pulse. The first interval is almost the same as or more than the second interval. Accordingly, the ink-droplet jetting apparatus is capable of jetting the ink droplets stably, and printing at a high speed.
