The ink-jet recording apparatus has an ink passage into which a water-based ink or a preservation solution is filled. The ink passage employs a rubber member formed from an ethylene propylene diene rubber in which a sulfenamide-based vulcanization accelerator or a thiazole-based vulcanization accelerator is employed. The water-based 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. Furthermore, 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 the maximum bubble pressure method at a measurement temperature of 25° C.
