Abstract
An inkjet recording apparatus according to an embodiment includes an ink jet head, a diaphragm-type first pump, a diaphragm-type second pump and a control device. The inkjet head ejects ink to an image receiving medium. The first pump supplies ink introduced from an ink storage section to the ink jet head. The second pump sucks ink that is not discharged from the ink jet head and discharges the sucked ink to a discharge chamber adjacent to a discharge section of the first pump at the upstream part of an ink supply path connected with the ink jet head. The control device drives the first pump and the second pump with same-phase driving voltage waveforms to make discharge timing of the first pump matching with that of the second pump.
