Abstract
A liquid droplet ejection device including: a liquid droplet ejection head including a nozzle, a supply channel, a discharge channel, a filter, and a communicating channel; and a liquid feeder that performs a liquid feeding operation causing the liquid in the supply channel and the discharge channel to flow in the liquid feeding direction. A mesh diameter of the filter is smaller than an aperture diameter of the nozzle, and the liquid feeder performs the liquid feeding operation in such a way that a pressure loss in the filter is smaller than a first meniscus break pressure at which a meniscus of the liquid ruptures in the filter.
