PROBLEM TO BE SOLVED: To provide an ink circulating-type inkjet device capable of discharging ink at high energy efficiency.SOLUTION: The inkjet device 100 has: an ink supply channel 101 through which ink flows; an ink chamber 110 communicated with the ink supply channel via an ink inlet channel 107, housing the ink supplied from the ink supply channel, and having a nozzle for discharging the ink; an ink discharging channel 102 communicated with an ink chamber via an ink outlet channel 108, wherein the ink discharged from the ink chamber flows; an ink circulating device for applying pressure to the ink so that the ink flows from the ink supply channel to the ink discharging channel through the ink chamber; and a first actuator 113 for vibrating the wall surface of the ink chamber. The inkjet device further has a second actuator 114 for changing the area of the lateral cross section of the ink outlet channel. |
