Summary:PROBLEM TO BE SOLVED: To obtain the thermal processor by which heat transfer to the image element is more uniformly attained by forcibly bringing the image element into heat conductive contact state with a continuous surface of a heat conductive material and arranging a heat source far away from the passage of the continuous surface. SOLUTION: An impermeable belt 20 made of chromium nickel is positioned on one side of a passage 18 on the downstream of an entrance 14. A lithographic plate 10, when moving along the passage 18, comes into contact with the belt 20. The heat source 26 is arranged far away from the passage 18 so as to heat the belt 20. A thermal block 32 is in heat conductive contact with the belt 20 through an intermediate area filled with heat-conductive copper/oil paste 33 on the opposite side of the belt 20 with respect to the passage 18. The configuration of the thermal block 32 is made so as to establish the relation between the positions and the umber of radiation type heaters 27 for securing nearly uniform heat conduction to the belt 20. The belt 20 is therefore heated to, for example, approximately 200 deg.C through heat conduction through the thermal block 32.
