Patent ID: 8596749

Claim:
A liquid ejection apparatus comprising: a liquid ejection head having an ejection face that has a plurality of ejection openings formed therein, the liquid ejection head being configured to eject liquid through the plurality of ejection openings to record an image on a recording medium, an ejection space being defined so as to face the ejection face; a humidification-liquid tank storing humidification liquid that has a nonvolatile component; a sealing mechanism configured to selectively establish (i) a sealing state in which the sealing mechanism seals the ejection space from an outside and (ii) an unsealing state in which the sealing mechanism does not seal the ejection space from the outside; and a humid-air supply mechanism configured to supply humid air into the ejection space when the sealing mechanism is in the sealing state, the humid air being an air humidified by the humidification liquid in the humidification-liquid tank, wherein the humidification-liquid tank is configured to be mountable on and removable from the humid-air supply mechanism, wherein a liquid layer constituted by the humidification liquid stored in the humidification-liquid tank and an air layer constituted by an air in the humidification-liquid tank are formed in the humidification-liquid tank, wherein the humidification-liquid tank has an upstream opening and a downstream opening that is formed so as to face the air layer, and wherein the humid-air supply mechanism includes a pump configured to discharge the humid air through the downstream opening.
