Abstract:
1. An ink jet recording apparatus comprising: a roll-set curl correcting section to correct a roll-set curl of a roll-state recording medium by applying heat and pressure, wherein the roll-set curl correcting section comprises a heating roller and a pressing roller installed to face the heating roller so as to nip the recording medium; a recording head to jet ink onto the recording medium; and a transporting section to transport an unrolled recording medium as the roll-set recording medium from a roll of rolled-recording medium wound around a core to the recording head via the roll-set curl correcting section so that the roll-set curl correcting section corrects the roll-set curl of the roll-set recording medium and thereafter the recording head jets ink onto the curl-corrected recording medium, wherein the pressing roller is a rubber roller and the heating roller is a metallic roller, and the hardness of the metallic roller is not less than 2 times the hardness of the rubber roller, and wherein the transporting section transports the recording medium such that the convex side of the roll-set curl of the recording medium faces the heating roller.
