Liquid feeding member for liquid ejection head, liquid ejection device, and image forming apparatus
Abstract:
A liquid ejection device ejects liquid droplets from a liquid ejection head. The liquid ejection device includes a liquid feeding member that feeds liquid to the liquid ejection head. The liquid feeding member is connected to a liquid ejection head to feed liquid to a common liquid chamber of the liquid ejection head, which liquid ejection head includes the common liquid chamber that supplies the liquid to plural individual liquid chambers communicating with plural nozzles that eject liquid droplets. The liquid feeding member includes a liquid circulation path through which the liquid circulates in a direction parallel to a direction in which the nozzles of the liquid ejection head are aligned.
