Abstract
An inkjet head includes a plurality of head units including a first head unit and a second head unit. Each head unit has a plurality of nozzles and a plurality of drive elements. The second head unit has an ejection performance of nozzles lower than an ejection performance of nozzles of the first head unit. The second head unit is farther from a center portion of the inkjet head than the first head unit is. A drive unit is configured to apply a drive voltage for generating energy to each of the plurality of drive elements included in each of the plurality of head units. The drive voltage applied to each of the plurality of drive elements included in the first head unit is lower than the drive voltage applied to each of the plurality of drive elements included in the second head unit.
