摘要： A method of driving a liquid ejecting head is provided. The liquid ejecting head varies pressure of a liquid in a pressure-generating chamber as a result of operating a pressure-generating element by supplying an ejection pulse, to eject liquid drops from a nozzle opening due to the pressure variation. The method includes performing a first contraction and performing a second contraction. In the first contraction, the liquid drops are ejected from the nozzle opening as a result of contracting the pressure-generating chamber. In the second contraction, the pressure-generating chamber is contracted so as to reduce withdrawal towards the pressure-generating chamber, of a meniscus after the ejection of the liquid drops A time from a start of the first contraction to a start of the second contraction is between ¼ to ¾ of a Helmholtz vibration period Tc of the pressure-generating chamber. A time of the first contraction is less than or equal to a natural vibration period Ta of the pressure-generating element.
