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 .gamma..sub.o of the coating liquid, a critical surface tension .gamma..sub.b of the conveyance member, and a surface tension .gamma..sub.i of the liquid that is ejected from the droplet ejection head satisfy the following equations (1) and (2). .gamma..sub.o<.gamma..sub.b (1) .gamma..sub.o<.gamma..sub.i (2)
