Negative pressure applying means for generating a meniscus in a nozzle hole through a balance with a negative pressure applied to an ink chamber via a restrictor part; pressurizing means for supplying pressurized ink to the ink chamber; withdrawal controlling means for drive-controlling an actuator for changing the volume in the ink chamber to withdraw the meniscus until the balance with the negative pressure is broken through the change of the volume in the ink chamber in response to the driving of the actuator; and recovery controlling means for, after the negative pressure applying means withdraws the ink in the ink chamber to the restrictor part, controlling the pressurizing means to supply the ink to the ink chamber and again generate the meniscus are provided. The pressurizing means pressurizes the ink under a pressure where the meniscus is not broken, and supplies the ink to the ink chamber.
