摘要： A liquid ejecting apparatus with a pressure chamber connected to an ejection nozzle that applies pressure to liquid that causes the liquid to be ejected from the nozzle. An actuator is provided to vibrate a free surface of the liquid in the nozzle without ejecting the liquid from the nozzle. A viscosity state judgment device judges the existence of a first viscosity state near the free surface of the liquid indicating that liquid ejection from the nozzle is possible without applying vibrations, a second state indicating that liquid ejection from the nozzle is possible if vibrations are applied, and a third state indicating that liquid ejection from the nozzle is not possible but restoration to the first state is possible if the vibrating action is performed. A control device then controls liquid ejection from the nozzle based on the judged state.
