Abstract
An inkjet recording apparatus includes a recording head including a first discharge port configured to discharge a first amount of ink droplets and a second discharge port configured to discharge a second amount of ink droplets smaller than the first amount, a cap, a suction unit, and a determination unit configured to determine whether to perform a first recording operation by using the first and second discharge ports or a second recording operation by only using the first discharge port. If the first recording operation is determined to be performed, the suction unit performs a first suction operation with a first strength and a second suction operation with a second strength higher than the first strength. If the second recording operation is determined to be performed, the suction unit is controlled not to perform the second suction operation and to perform the first suction operation.
