<p>PROBLEM TO BE SOLVED: To provide a liquid droplet jet apparatus capable of suppressing increment of an ink viscosity which is capable of being suppressed by a little vibration drive for preventing the increment of the ink viscosity in a vicinity of a nozzle in a liquid droplet jet recording method.SOLUTION: A liquid droplet jet head includes: an ink droplet discharging unit for discharging a liquid droplet from a nozzle; a waveform outputting unit for outputting a waveform for driving the ink droplet discharging unit to the ink droplet discharging unit; a signal measuring unit for measuring a consecutive number of printing signals for discharging one drop of the liquid droplet at one printing cycle; and a waveform control unit for comparing the consecutive number to a predetermined threshold value and varying the printing signal for discharging the one drop of the liquid droplet to a printing signal for discharging multiple liquid droplet with respect to a printing signal for printing a first row of a printing surface parallel to an arrangement direction of the nozzles when the consecutive number is smaller than the threshold value.</p> |
