摘要: An ink-jet recording apparatus having an ink-jet recording head including pressure generating chambers communicatively connected to a nozzle opening and a reservoir, pressure generating member for pressurizing the pressure generating chambers, and a control device for applying drive signals to the pressure generating member. The control device applies drive signals to the pressure generating member. The drive signals contain signals corresponding to print data and signals which minutely vibrate the meniscus of ink in the nozzle openings to such an extent as to not eject ink droplets during a nonprint period. The control device causes ejection of ink droplets from the nozzle openings in accordance with print data during printing operations, and minutely vibrates the meniscuses of ink formed at the nozzle openings a preset period of time before or after the discharging of the ink droplets in a printing operation.
