Abstract: Provided is an inkjet recording apparatus that causes a recording head to execute appropriate flushing based on the presence or absence of a non-ejecting nozzle in order to reduce deterioration of the image quality of recorded images or to improve the ejection failure of a non-ejecting nozzle at an early stage. When the recording head executes a first flushing, a control unit of the inkjet recording apparatus determines the presence or absence of a non-ejecting nozzle based on a detection result of an ejection detection unit. Then, based on the determination result, the control unit selects whether or not to perform a second flushing. In the second flushing, the recording head is caused to eject ink at timing at which a recording medium on the conveyor belt faces the recording head due to traveling of the conveyor belt.
