Abstract: A liquid ejection device includes an ink jet head in which a plurality of nozzle portions are arranged in a matrix; a plurality of pressurizing elements that generate an ejection force; and a driving voltage supply unit that supplies a driving voltage to the pressurizing elements. In the device, the ink jet head is provided with supply flow paths, the nozzle portions which are supplied with the liquid from the same the supply flow path are divided into two or more groups, the driving voltage supply unit supplies an ejection driving voltage for ejecting the liquid to each of the groups when a dummy jet is performed, and during a period of time when the dummy jet is performed for one group, the driving voltage supply unit supplies a non-ejection driving voltage for preventing the liquid from being ejected to the other groups.
