Patent ID: 7413287

Claim:
A liquid discharging apparatus which discharges a liquid having an electroconductivity, comprising: a liquid channel which has a discharge port and through which the liquid flows; an electrode which is formed on a predetermined surface of the liquid channel, and which is extended from the discharge port toward an upstream side of a direction of a flow of the liquid; an insulating film which is extended from the discharge port toward the upstream side of the direction of the flow on the predetermined surface of the liquid channel, and which is formed on the predetermined surface of the liquid channel entirely in a width direction orthogonal to the direction of the flow, and which covers the electrode; an adjacent area which is adjacent to the insulating film on the predetermined surface of the liquid channel on the upstream side of the direction of flow; and an electric potential control mechanism which controls an electric potential of the electrode; wherein a liquid repellence of the insulating film is higher than a liquid repellence of the adjacent area.
