ABSTRACT:
There are disclosed an elastic member for an ink-jet recording apparatus which member is composed of a material comprising at least one copolymer (thermoplastic elastomer) constituted of at least one polymer block containing a vinyl aromatic compound as an principal component and at least one polymer block containing a conjugated diene compound as an principal component, the material further having 1-50 parts by weight of a polyolefin resin and 1-500 parts by weight of a softening agent based on 100 parts by weight of the copolymer. The elastic member is well suited for use in an ink tank as an ink tank valve for supplying a recording head with the ink to be filled in the ink chamber, for use as a sealing member which is installed at an ink supply port and prevents the ink from leaking through the ink supply port, and further for use as a sealing member which is installed on the main body of the ink-jet recording apparatus and prevents the ink from leaking through the recording head.
