发明名称 LIQUID DISCHARGE HEAD, LIQUID DISCHARGE DEVICE, AND IMAGE FORMATION APPARATUS
摘要 PROBLEM TO BE SOLVED: To provide a liquid discharge head, a liquid discharge device, and an image formation apparatus that can prevent an ink droplet from being not discharged or from being discharged in a bent discharge direction owing to blocking of a nozzle hole with viscosity-increased ink.SOLUTION: A liquid discharge head includes a nozzle plate where a liquid discharge surface for discharging recording liquid through nozzle holes is formed, and an outer periphery of the nozzle plate is covered with a nozzle cover. The nozzle cover is inclined toward an opening part of the nozzle cover so that the opening part of the nozzle cover is closer to the liquid discharge surface of the nozzle plate than to an outer peripheral part of the nozzle cover, and has an inclined surface, more in parallel with the liquid discharge surface than with a plane perpendicular to a thickness direction of the nozzle cover, at the tip of the opening part of the nozzle cover, and a resin material is so embedded as to cover the inclined surface and to fill a gap between the inclined surface and nozzle plate.
