ABSTRACT:
An image recording apparatus of the present invention comprises an inkjet head which includes a nozzle plate where a plurality of nozzles that shoot ink are arranged in a column and an ink chamber which retains ink and is connected to the plurality of nozzles, at least one maintenance suction section which has a suction area larger than the nozzles, a suction section driving mechanism which causes the suction area to face the nozzles and moves the suction section relatively in the nozzle arrangement direction; and a positive pressure applying section which applies a positive pressure to the ink chamber. The maintenance suction section sucks in ink near the nozzles as moving in the nozzle arrangement direction, while the positive pressure is being applied to the ink chamber.
