Abstract:
An ink jet recording apparatus includes a recording head having a nozzle arrangement region in which a plurality of nozzles for discharging ink is arranged, and a cleaning unit configured to perform cleaning operation on the recording head. A control unit is configured to control the cleaning unit and a change operation for changing relative position relation between a region where the record medium passes and the nozzle arrangement region. The control unit acquires end passage positions in a first recording operation before the change operation is performed, and a passage region in a second recording operation after the change operation is performed. The control unit performs control for executing the cleaning operation in a case where the end passage position is included in the passage region.
