Patent ID: 8191994

Claim:
A liquid ejection head comprising: a nozzle member having a plurality of nozzles to eject ink droplets, the plurality of nozzles being arranged in a two dimensional manner along a first direction and a second direction different from the first direction; a charging member having a charging electrode to charge ink droplets ejected from each of the plurality of nozzles; and a first deflection member and a second deflection member, each having a deflection electrode to deflect each of the ink droplets charged by the charging electrode, wherein each of the charging member, the first deflection member, and the second deflection member have through-holes that the ink droplets ejected from the plurality of nozzles pass through, the charging member, the first deflection member, and the second deflection member are laminated in this order in a direction in which the ink droplets are ejected from each of the plurality of nozzles, and the first deflection member includes a projection portion that projects toward each of the through-holes of the second deflection member and a conductive surface comprising the deflection electrode.
