A fluid ejecting apparatus includes a pressure chamber, a pressure generating element that change a volume of the pressure chamber, a nozzle, and a control unit that generates a drive pulse for controlling the pressure generating element, wherein the control unit is able to generate a maintenance drive pulse (300) for discharging unnecessary bubbles together with the fluid from the pressure chamber, wherein the maintenance drive pulse includes a first pulse portion (Pcw) to cause the pressure chamber to expand into an expanded state, a second pulse portion (Pwh) that keeps the expanded state for a predetermined period of time, and a third pulse portion (Pwd) that causes the pressure chamber to contract from the expanded state, wherein the pulse width of the first pulse portion (Pcw) is set to be equal to or smaller than half the Helmholtz resonance period of the fluid with which the pressure chamber is filled.
