Abstract
A multi-color injection molding process for producing an ink-jet printer member having a plastic substrate and an elastic material layer that are integrally composited, by melt-injecting into a mold in turn, a material for a plastic substrate and an elastic material composed of a thermoplastic elastomer. The above process is well suited for the production of the ink-jet printer member such as an ink tank valve for supplying a recording head with an ink to be filled in an ink chamber, also of a sealing member which is installed at an ink supply port or on the main body of an ink-jet printer and prevents an ink from leaking through the ink supply port or through the recording head.
