Liquid discharge head and image forming apparatus

摘要

A liquid discharge head includes a nozzle that discharges liquid droplets, a common liquid chamber that supplies liquid to an individual liquid chamber that is in communication with the nozzle, and a filter plate that is arranged in a liquid flow path of the common liquid chamber. The filter plate includes a filter part that filters the liquid and a damper part that reduces a pressure variation in the common liquid chamber, and the filter part is arranged to be thicker than the damper part.

主权项

1. A liquid discharge head comprising:
plural nozzles arranged in a nozzle alignment direction, a nozzle amongst the plural nozzles being configured to discharge liquid droplets in a liquid discharge direction; a common liquid chamber that supplies liquid to an individual liquid chamber that is in communication with the nozzle; and a filter plate that is arranged in a liquid flow path of the common liquid chamber and filters the liquid that passes in a liquid flow path direction through the filter plate, the filter plate including
a filter hole arrangement portion that includes plural filter holes and has a thickness in a thickness direction parallel to the liquid flow path direction, anda damper wall that does not include any of the filter holes and that reduces a pressure variation in the common liquid chamber; wherein a thickness of the damper wall of the filter plate in the thickness direction is thinner than that of the filter hole arrangement portion of the filter plate.
