Abstract
An ink jet recording apparatus includes a cap, a control unit, and a recording unit having nozzle arrays each including a plurality of nozzles for ejecting ink in an image recording operation. The cap receives ink preliminarily ejected from the recording unit. The control unit controls an ejection operation to eject ink in response to receiving a recording command to cause an amount of ink ejected from a first nozzle group in a first preliminary ejection executed prior to the recording operation of the image to be smaller than an amount of ink ejected from a second nozzle group different from the first nozzle group in a second preliminary ejection executed prior to the recording operation of the image in a case where the recording command includes an instruction for recording the image by using the second nozzle group without using the first nozzle group among the plurality of nozzles.
