Abstract

A droplet ejection device includes: a droplet ejection head that ejects a droplet to a recording medium; an irradiating portion that evaporates moisture of the droplet landed on the recording medium by irradiating the recording medium with infrared laser beam; and a light shielding member that includes an upper light shielding member provided on a perimeter of the irradiating portion and a lower light shielding member provided on a position facing the irradiating portion and the upper light shielding portion while placing the recording medium therebetween, in which the upper light shielding portion and the lower light shielding portion are in contact with each other at an outside of the recording medium in the width direction so that the light shielding member shields the infrared laser beam at least in the width direction of the recording medium.
