Abstract:
A liquid ejection head having: a nozzle for ejecting a liquid; a flat nozzle plate on which the nozzle is provided; a cavity to store the liquid to be ejected from an ejection hole of the nozzle; a pressure generating section which generates pressure on the liquid in the nozzle and forms a meniscus of the liquid in the ejection hole of the nozzle; an electrostatic voltage applying section which applies electrostatic voltage between a base material and the liquid in the nozzle and the cavity, and generates electrostatic suction force; and an operation control section which controls applying of the electrostatic voltage by the electrostatic voltage applying section, and controls applying of drive voltage to drive the pressure generating portion, wherein a volume resistivity of the nozzle plate is 1015 Ωm or more.
