> The ink storage pipe includes an at least two-layer structure of an inner layer in contact with ink and a base layer, the base layer being formed of a paper base material and the inner layer being formed of a resin. The resin is preferably an acrylic resin, polystyrene, a fluorine resin, silicone or a mixture thereof.
> In case of applying a resin film, the inner layer 4 has a thickness of typically 3 to 90 micrometre and preferably 5 to 60 micrometre.
