发明名称 Liquid discharge head for inkjet printer
摘要 A liquid discharging head includes: a plurality of nozzles 104 that discharge liquid droplets; and a plurality of piezoelectric elements 130 that generate pressure for discharging liquid droplets from the respective nozzles, wherein the piezoelectric elements are subjecyed to a repolarization process to set the non-uniformity of the droplet discharging characteristics of the nozzles to be in a predetermined range by combining adjustment of a polarization sensitivity and adjustment of a polarization voltage for each of the piezoelectric elements.
