ABSTRACT:
An ink-jet recording apparatus is provided which includes an ink-jet head having a plurality of ink chambers and a common ink chamber which communicates with each of the plurality of ink chambers to supply ink to the plurality of ink chambers, the ink-jet head maintaining the plurality of ink chambers at a negative pressure in image recording, selecting one of the plurality of ink chambers on the basis of printing data and causing change in volume of the selected ink chamber, and thereby performing image recording by discharging the ink from a nozzle, and a pressure section which applies a positive pressure to the plurality of ink chambers when the ink-jet head is in a left state, the positive pressure being a pressure at which the ink is not discharged from the nozzle.
