ABSTRACT:
An ink jet recording apparatus includes a recording head having a discharge port for discharging ink, a liquid chamber communicating with the discharge port, a supply port provided in the liquid chamber for supplying ink to the liquid chamber, a communication port provided in the liquid chamber, and an air chamber communicating with the liquid chamber through the communication port to define a closed space in communication only with the liquid chamber. The cross-sectional area of the communication port is smaller than both the cross-sectional area of the air chamber and the area of the wall of the liquid chamber on which the communication port is located.
