Abstract
An inkjet recording apparatus capable of determining an amount of bubbles in an ink flow path and performing suction recovery operation at an appropriate timing is provided. The inkjet recording apparatus includes a recording head including a nozzle for discharging ink and a flow path forming member forming an ink flow path for supplying the ink to the nozzle, a suction unit configured to suck the ink from the recording head, and a temperature detection unit configured to detect a temperature in the recording head. The inkjet recording apparatus includes a control unit configured, based on an amount of gas in the flow path forming member before the ink is filled in the ink flow path, and an amount of gas in equilibrium in the flow path forming member after the ink is filled in the ink flow path, to control the operation of the suction unit.
