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 employs a rubber member formed from a rubber in which a butyl rubber polymer serving as a base polymer, zinc oxide serving as a vulcanization agent and a thiazole-based compound serving as a vulcanization accelerator are employed. The water-based ink includes at least a coloring agent, water and a glycol ether, an amount of the glycol ether being about 5 wt. % to about 10 wt. % with respect to the total weight of the water-based ink. The preservation solution includes at least water and a glycol ether, an amount of the glycol ether being about 5 wt. % to about 10 wt. % with respect to the total weight of the preservation solution.
