Abstract
An ink-jet printer for forming desired characters on a recording medium by ink droplets is provided. In accordance with the present ink-jet printer, the third harmonic vibration as well as the fundamental harmonic vibration is imparted to the ink inside the ink nozzle so that ink droplets regularly spaced from each other without ink satellites therebetween may be produced. One embodiment of the present invention proposes to provide a vibrator having a resonant frequency three times higher than the exciting frequency. Another embodiment of the present invention proposes to mount the vibrator on the nozzle at a specific location with respect to the mouth of the nozzle.
