摘要： A liquid ejection head includes a plurality of ejection orifices, liquid chambers, piezoelectric actuators, and driving units, and a control unit. Each ejection orifice ejects liquid, each liquid chamber communicates individually with an ejection orifice, each piezoelectric actuator is disposed individually for a liquid chamber and generates energy to eject liquid, and each driving unit individually drives a piezoelectric actuator. The control unit controls each driving unit to output a first voltage pulse to eject liquid or a second voltage pulse to vibrate a meniscus of liquid in a state in which the meniscus is held in a liquid chamber. The control unit selects ejection orifices used to eject liquid and controls to output the first voltage pulse to them, and selects ejection orifices not used to eject liquid and controls to output the second voltage pulse to them to perform respective concurrent recording and recovery operations.

摘要： An ink jet recording apparatus includes a recording head having one nozzle array or a plurality of nozzle arrays. Each nozzle array includes a plurality of nozzles. These nozzles include at least one end nozzle at at least one end of the nozzle array or arrays and ink nozzles other than the at least one end nozzle. The end nozzle discharges a windshield liquid and the ink nozzles discharge ink. The end nozzle prevents the displacement on a recording medium of ink droplets discharged from the outermost ink nozzle among the ink nozzles, thus forming a high-quality image without partial unevenness in recording density.
