Abstract
An inkjet recording apparatus includes a recording unit, a first ink storage unit, a second ink storage unit, a discharge unit, a first detection unit configured to detect that an amount of the ink stored in the first ink storage unit is below a first predetermined amount, and a second detection unit configured to detect that an amount of the ink stored in the second ink storage unit is below a second predetermined amount. The inkjet recording apparatus further includes a control unit configured to control the discharge operation after the detection by the first detection unit and the detection by the second detection unit based on a detection timing of the first detection unit and a detection timing of the second detection unit.
