Abstract
A droplet ejection device includes a droplet ejection head, a conveyance member, a cleaning unit and a coating unit. The droplet ejection head ejects droplets. The conveyance member retains a recording medium and conveys the recording medium to oppose the droplet ejection head. The cleaning unit cleans the conveyance member. The coating unit applies a coating liquid, with a characteristic of repelling the liquid that is ejected from the droplet ejection head, onto the conveyance member. A surface tension γof the coating liquid, a critical surface tension γof the conveyance member, and a surface tension γof the liquid that is ejected from the droplet ejection head satisfy the following equations (1) and (2).γ<γ  (1)γ<γ  (2)
