A fluid ejection device (1) includes: a fluid chamber (80) a volume varying unit (30,40) configured to vary the volume of the fluid chamber a fluid supplying unit (10) configured to supply fluid to the fluid chamber at a predetermined pressure and an ejection command switching unit (26) configured to switch a fluid ejection between a pulsed flow ejection which ejects the fluid in a pulsed manner by activating the volume varying unit and varying the volume of the fluid chamber and a continuous flow ejection which ejects the fluid with a fluid supply pressure from the fluid supplying unit higher than that in the case of the pulsed flow ejection in a state in which the volume varying unit is stopped.
