A pressure generating element is associated with a pressure chamber communicated with a nozzle orifice. The pressure generating element is operable to generate pressure fluctuation in liquid contained in the pressure chamber to eject a liquid droplet from the nozzle orifice, when a drive signal is supplied thereto. An identifier is provided with ID information including a first deviation of an ejected liquid amount from a designed value when a drive signal at a first, regular drive frequency is supplied, and a second deviation of an ejected liquid amount from the designed value when a drive signal at a second, operable maximum drive frequency is supplied.
