Abstract:
A liquid discharge head includes a plurality of nozzles, a plurality of individual liquid chambers, a common liquid chamber, a deformable damper, and a damper chamber. The plurality of nozzles is arrayed in a nozzle array direction, to discharge liquid. The plurality of individual liquid chambers is communicated with the plurality of nozzles. The common liquid chamber supplies liquid to the plurality of individual liquid chambers. The deformable damper constitutes part of a wall face of the common liquid chamber. The damper chamber is disposed along the nozzle array direction with the damper interposed between the damper chamber and the common liquid chamber. The damper chamber extends to an outer area in the nozzle array direction than an individual liquid chamber of the plurality of individual liquid chambers at each end in the nozzle array direction.
