COATING DEVICE AND IMAGE FORMING SYSTEM

原文（中国語）

A coating device includes a reservoir to store a coating liquid, a coating roller to coat a sheet with the coating liquid, a pressure roller to contact the coating roller, a separator to bring and separate the pressure roller into contact with and from the coating roller, a supply unit to supply the coating liquid to the reservoir, a drain unit to drain the coating liquid from the reservoir, a liquid level detector to detect that a liquid level of the coating liquid is below a non-supply position, and circuitry. The circuitry controls the drain unit to drain the coating liquid after a power-off of the coating device, controls the separator to bring the pressure roller into contact with the coating roller after a detection of the liquid level below the non-supply position, and rotate the pressure roller and the coating roller for a predetermined time as an idle rotation.
