Abstract
The flow path resistances of ink feeding holes () of this pressure-type inkjet head () differ from each other. When ink is not being discharged, a driver circuit () generates a driving signal for circulating ink, which differs from a driving signal for discharging ink, and applies the driving signal for circulating ink to an actuator (). The actuator () causes the flow rate of ink flowing from the respective ink feeding holes () to differ between when ink is being drawn into a pressure chamber () and when ink is being discharged from the pressure chamber () and circulates the ink within the pressure chamber () by being driven on the basis of the driving signal for circulating ink.
