Abstract
A liquid ejecting apparatus includes a liquid ejecting head having a nozzle that ejects liquid and a pressure chamber in communication with the nozzle. A pressure generator causes pressure fluctuation in the liquid retained in the pressure chamber. The liquid ejecting head is capable of ejecting the liquid from the nozzle as a result of operation of the pressure generator. A driving signal generating section generates a driving signal having an ejection pulse for driving the pressure generator to eject the liquid from the nozzle. The ejection pulse is a voltage waveform four waveform portions having, respectively, voltage levels V, V, Vand Vthat satisfy the following conditions (A) and (B).0≦3≦0.4×2  (A)0.2×2≦4≦2  (B)
