PROBLEM TO BE SOLVED: To provide a heating device capable of performing the heating processing of a printing plate without forming a stripe or the like on the surface of the printing plate. SOLUTION: This heating device 200 is equipped with a heating part 102 heating the printing plate 120 provided with a photosensitive layer on a metallic supporting body by carrying it in heat atmosphere radiated from a heat source, an upstream side carrying roller and a downstream side carrying roller 10 consisting of a pair of rollers carrying the printing plate 120 while interposing it from upside and downside and arranged on the upstream side and the downstream side of the heating part. At least either roller constituting the downstream side carrying roller 10 has a driving shaft 11 and a center hole through which the driving shaft is inserted and is equipped with plural disk-like members 12 attached to the driving shaft. The disk-like member 12 is constituted to restrain the deformation of the printing plate due to expansion or make the printing plate pass without crushing the deformed part due to the expansion. |
