A liquid ejecting apparatus includes an ejecting section that includes nozzle, a pressure chamber, and a drive element that is configure to generate pressure fluctuation in the liquid in the pressure chamber in response to a supplied drive signal. The drive signal includes a first ejection pulse for ejecting the liquid from the nozzle. The first ejection pulse includes a first depressurized-potential change component to reduce pressure of the liquid in the pressure chamber, and a first pressurized-potential change component to increase the pressure of the liquid in the pressure chamber to protrude a liquid surface from the nozzle after the first depressurized-potential change component. A potential change range of the first depressurized-potential change component is 40% or more of a potential change range of the first pressurized-potential change component. A potential change rate of the first depressurized-potential change component is 1 V/μsec or more and 2 V/μsec or less.
A liquid ejecting apparatus comprising:
A driving method for driving a liquid ejecting apparatus including an ejecting section that includes a nozzle which ejects a liquid, a pressure chamber which communicates with the nozzle, and a drive element which is driven so as to generate pressure fluctuation in the liquid in the pressure chamber in response to a supplied drive signal and a drive signal generation circuit that is configured to generate the drive signal, wherein
