Abstract:
1. A liquid discharge head comprising: a plurality of nozzles disposed on a nozzle surface to discharge liquid droplets; a plurality of individual liquid chambers in communication with the nozzles; a plurality of liquid supply paths in communication with the individual liquid chambers; a common liquid chamber member forming a common liquid chamber in communication with the liquid supply paths; and a filter unit including openings, disposed in the liquid supply paths between the individual liquid chambers and the common liquid chamber, wherein liquid is supplied from a direction from the common liquid chamber to the liquid supply paths, the direction crossing a liquid flow direction of liquid flowing in the liquid supply paths, and wherein in a wall surface of the common liquid chamber member facing the common liquid chamber on a side closer to the individual liquid chambers in a direction that is orthogonal to a nozzle array direction, an inclined surface forming an oblique angle relative to the nozzle surface is formed in a manner that a width of the common liquid chamber in the direction that is orthogonal to a nozzle array direction and parallel to the liquid flow direction in the liquid supply paths gradually expands toward the liquid supply paths, wherein the openings of the filter unit are disposed, in a direction that is parallel to a droplet discharge direction and orthogonal to the nozzle array direction, between the nozzles and the inclined surface of the common liquid chamber member.
