Abstract
An ink jet recording head has a plurality of ink-discharge electrodes and control electrodes and an opposed electrode arranged at a fixed spacing and grounded. A pulse voltage with a reversed polarity is applied to the control electrodes in synchronization with the superimposition of the pulse voltage on a bias voltage applied to the ink-discharge electrode when the ink is discharged. As a result, an ink jet recording apparatus, which can decrease the pulse voltage needed to discharge the ink, is provided with a simple configuration.
