Patent ID: 8585199

Claim:
An ink jet recording system, comprising: a recording head that ejects ink to the surface of a target non-ink-absorbing or low ink-absorbing recording medium; a medium support portion that faces the recording head and supports the target recording medium from the back surface; a drying portion as a first fixing portion that evaporates a liquid ingredient of the ink that is ejected to the target recording medium from the recording head and adheres thereto, the drying portion being integrated into the medium support portion; and a second fixing portion at the downstream side with respect to the drying portion and the recording head of a feeding direction of the target recording medium, the feeding direction at which the second fixing portion is arranged being orthogonal to the medium support portion, the ink at least containing: (1) a coloring agent; (2) a monomer which is an organic solvent having a boiling point in a range of 100° C. to 250° C.; (3) a polymerizable oligomer and/or polymer; and (4) a photopolymerization initiator, the second fixing portion being an irradiation device that irradiates the target recording medium with ultraviolet ray or electron beam, and the evaporation amount of the liquid ingredient in the drying portion being 40 to 70% by weight of the ink adhering to the target recording medium.
