Abstract:
A liquid ejecting apparatus includes: a pressure chamber that communicates with a liquid supply section and a nozzle; an element that changes a pressure of liquid within the pressure chamber; and an ejection pulse generation section that generates an ejection pulse for operating the element in order to eject the liquid from the nozzle. In the apparatus, the viscosity of the liquid is not less than 8 millipascal seconds. The nozzle has a first portion in which a liquid ejection side thereof has a smaller opening area than a pressure chamber side thereof, and a second portion which communicates with an ejection side end portion of the first portion. In addition, the ejection pulse has a depressurizing portion for depressurizing the liquid in order to attract a meniscus positioned on the second portion to the first portion, and a pressurizing portion for pressurizing the liquid in order to eject the liquid before the meniscus attracted to the first portion returns to the second portion.
