The ink-jet recording apparatus employing an elastic member in at least a
part of an ink passage into which a water-based ink for ink-jet recording
is filled is configured to satisfy the following inequality (1):
(T.sub.1/T.sub.0).times.100.ltoreq.about 200% (1), wherein T.sub.1 is
filtration time when a first ink is filtrated through a specific
electroformed filter, the first ink being prepared by immersing an
elastic member in a water-based ink for ink-jet recording under a
prescribed condition, and T.sub.0 is filtration time when a second ink is
filtrated through the electroformed filter having same specifications as
the above-mentioned filter, the second ink under another condition.
