ABSTRACT:
The ink-jet recording apparatus has an ink passage into which a water based ink or a preservation solution is filled. The ink passage is formed from a rubber employing organic peroxide and zinc oxide as a vulcanization agent. The ink has a dynamic surface tension at a lifetime of 100 ms of about 35 mN/m to about 45 mN/m as measured by means of a maximum bubble pressure method at a measurement temperature of 25° C. The preservation solution has a dynamic surface tension at a lifetime of 100 ms of about 30 mN/m to about 35 mN/m as measured by means of a maximum bubble pressure method at a measurement temperature of 25° C.
