<P>PROBLEM TO BE SOLVED: To provide a heat drum capable of shortening the leading time, unifying the temperature of a warm temperature surface, and enhancing productivity. <P>SOLUTION: The heat drum comprises a cylindrical drum body 43 having a rotary shaft 40, a heater 60 disposed inside the drum body 43, a warm temperature surface formed on an outer surface of the drum body 43, a heating medium chamber 80 provided in the drum body and to store a liquid heating medium to transfer the heat of the heater 60 to the outer surface, and a stirring blade 72 to stir an oil 81 in the heating medium chamber 80. The heater 60 is disposed inside the rotary shaft 40, and the stirring blade 72 is rotated around the rotary shaft 40. When the oil 81 is mixed by the stirring blade 72, as the temperature is rapidly and uniformly raised, the leading time can be shortened thereby. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
