Abstract:
A liquid discharge head includes a nozzle plate, a channel plate, a wall member, and a common liquid chamber. The nozzle plate includes nozzles, and the channel plate forms a plurality of individual channels communicating with the nozzles. The wall member forms at least one portion of a wall of the plurality of individual channels. The common liquid chamber, arranged at a side opposite the plurality of individual channels, supplies liquid to the individual channel. The wall member includes a deformable damper area, a reinforced area, and an area of reduced thickness. The damper area forms one portion of a wall of the common liquid chamber, and the reinforced area divides the damper area into plural areas. The area of reduced thickness, arranged in at least one portion of the reinforced area, has a thickness greater than the damper area and less than the reinforced area.
