Abstract:
A liquid discharge head includes a plurality of nozzles, a plurality of individual liquid chambers, a circulation channel, a circulation common liquid chamber, a common liquid chamber, and a vibration damping member. The plurality of nozzles discharges liquid. The plurality of individual liquid chambers is communicated with the plurality of nozzles. The circulation channel is communicated with the plurality of individual liquid chambers. The circulation common liquid chamber is communicated with the circulation channel. The common liquid chamber supplies the liquid to the plurality of individual liquid chambers. The common liquid chamber includes a first portion disposed side by side with the circulation common liquid chamber in an in-plane direction and a second portion having a width greater than a width of the first portion in the in-plane direction. The vibration damping member is recoverably deformable and constitutes a wall surface of the second portion of the common liquid chamber.
