Abstract: A fiber body which exhibits sufficient ink supplying characteristics for keeping up with the trend toward diversification of ink and high printing speed while ensuring an easy and simple ink injection operation and a liquid container having the same. The ink tank 1 has a PP fiber body (crosshatched area of the figures) 2, as a negative pressure generating member for an ink jet head which ejects liquid to perform recording, arranged almost all over the interior thereof, so as to allow the fiber body to hold a liquid to be supplied to an ink jet head. On the top of the tank casing, provided is an atmosphere communication port 3. And as a PP fiber body 2, used is an assembly of intertwined PP fibers of which surface has been subjected to surface treatment of giving hydrophilic nature thereto.

Abstract: To provide a recording liquid feed path, recording liquid container, and recording liquid feed device having the same, as well surface modifying method for the recording liquid feed device to feed efficiently a recording liquid for ejection through a feed tube. If the interior of the feed tube is not rendered hydrophilic as shown in Fig. 3A, air which has passed through a wall of the feed tube forms a bubble, which bubble adheres to an inner surface of the feed tube and obstructs a flow of the recording liquid. But if the inner surface of the feed tube is rendered hydrophilic to form a hydrophilic surface as shown in Fig. 3B, the recording liquid is conducted along the hydrophilic surface at the inner surface portion of the feed tube with the bubble adhered thereto, so that the adhesion area of the bubble to the feed tube inner surface is reduced and the bubble floats from the inner surface. Consequently, when the recording liquid is fed, the bubble can be removed easily by the flow of the recording liquid and thus the flow of the recording liquid can be prevented from being obstructed by the bubble.
