Abstract: Fluid is pressurized and supplied to a fluid chamber with a fluid pressurizing and supplying unit. The pressurized fluid within the fluid chamber is ejected through an injection nozzle by reduction of the volume of the fluid chamber caused by applying a driving voltage to a volume varying unit. In applying the driving voltage to the volume varying unit, the effect imposed on fluid injection by pressure fluctuations of the fluid pressurized and supplied to the fluid chamber is compensated by changing the voltage waveform of the driving voltage. When the pressure of the supply flow amount is decreased to a pressure lower than a predetermined pressure, the time intervals of the driving waveform are corrected. The maneuverability of a fluid injection device does not deteriorate even when the pressure of the fluid pressurized and supplied to the fluid chamber fluctuates.
