The present invention provides an ink drying prevention apparatus that can prevent ink within an ink-jet recording head from drying, for a long period of time. The ink drying prevention apparatus prevents ink within an ink-jet recording head from drying, and includes a porous substance permeated with a seal liquid that is nonvolatile and incompatible with the ink within the head, wherein the porous substance can contact a nozzle surface of the ink-jet recording head. The seal liquid forms plural meniscuses in an interface with the nozzle surface and inside the porous substance to block air paths, thereby preventing ink within a nozzle exposed to the nozzle surface from drying.
