An ink jet recording apparatus has a recording head 22 having pressure chambers to which ink is supplied, pressure generation elements for generating pressure in the pressure chambers, and nozzle orifices 8 communicating with the pressure chambers for jetting ink drops, a cap 24 for sealing a nozzle face 40 of the recording head 22 while defining an internal space therein, and a suction pump for giving negative pressure to the internal space of the cap 24, and the cap 24 contains a cover member 33 for covering all nozzle orifices 8 with the cap 24 sealing the nozzle face 40, whereby bubbles occurring in the internal space of the cap 24 are prevented from adhering to the nozzle face 40 and entering the nozzle orifices 8 and a print failure is prevented from occurring.
