LIQUID-SUPPLY APPARATUS AND IMAGE-FORMING SYSTEM INCLUDING LIQUID-SUPPLY APPARATUS

摘要

A liquid-supply apparatus is disclosed. The apparatus supplies liquid to be applied onto a recording medium to a liquid-supply pan. The liquid-supply apparatus comprises a temporary-storage room arranged lower than a liquid surface of the liquid-supply pan, the temporary-storage room storing the liquid inside the liquid-supply pan by temporal evacuation, an evacuation line connecting the liquid-supply pan and the temporary-storage room, the evacuation line being a flow channel for the liquid during evacuation, an evacuation-line opening and closing member opening and closing the evacuation line, and a controller controlling an opening and closing operation of the evacuation-line opening and closing member. The liquid surface in the temporary-storage room is in a position lower than that of the liquid-supply pan. The controller controls the operation of the evacuation-line opening and closing member so as to fill the evacuation line with the liquid as an auxiliary operation just before the evacuation.
