Abstract
Provided is a continuous-type charge deflection liquid ejection head that is suitable for higher-density and multiple nozzles. This liquid ejection head includes: an orifice plate having a plurality of nozzles arranged in a two-dimensional manner; a charging electrode plate having a charging electrode to charge ink droplets from each of the plurality of nozzles; and first and second deflection electrode plates each having a deflection electrode to deflect each of the ink droplets charged by the charging electrode, in which each of the charging member, the first deflection member, and the second deflection member has through-holes that ink droplets pass through, and the charging member, the first deflection member, and the second deflection member are laminated in this order in an ejecting direction of the ink droplets.
