Abstract
An ink jet recording apparatus includes: a first pump configured to supply ink introduced from an ink storage section to an ink jet head; a second pump configured to suck ink and discharge the sucked ink to a discharge chamber; and a control device configured to drive 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, wherein an ink flowing path from the discharge section of the first pump to a center part of the discharge chamber and an ink flowing path from the discharge section of the second pump to the center part of the discharge chamber have the same length as each other and have the same cross-sectional shape as each other.
