Patent ID: 7934786

Claim:
A liquid ejecting apparatus comprising: a liquid ejecting head including pressure generation chambers communicating with nozzle openings for ejecting a liquid and pressure generation units which cause pressure variations in the pressure generation chambers; and a driving unit which supplies, to the pressure generation units, a driving signal including an expansion element for expanding the pressure generation chambers, the expansion element beginning at an intermediate voltage potential level and rising to a first voltage potential level that is greater than the intermediate voltage potential level, a contraction element for contracting the pressure generation chambers, the contraction element beginning at the first voltage potential level and falling to a second voltage potential level that is less than the intermediate voltage potential level, and a re-expansion element for expanding the pressure generation chambers before the liquid is ejected from the nozzle openings by the contraction element so as to eject the liquid, the re-expansion element beginning at the second voltage potential level and rising to a third voltage potential level that is greater than intermediate voltage potential level and less than the first voltage potential level, wherein the re-expansion element includes a primary expansion element which is provided at the contraction element side so as to expand the pressure generation chambers, and a secondary expansion element which has at least a variation portion having a voltage variation ratio different from a voltage variation ratio of the primary expansion element in continuation to the primary expansion element and expands the pressure generation chambers.
