Abstract (en)
A roller having a solid or hollow roller body (3) and one or more heat pipes (10) disposed along a central axis of the roller body from its one end. A portion (12) of the heat pipe is extended from the roller body (3). The extended portion (12) of the heat pipe has thereon a radiation device (13) which is prepared as to be a fin type. When heating the roller, the extended portion (12) of the heat pipe (10) will be utilized as an heat-inlet section, so that the applied heat is transmitted to the roller body (3). While, cooling the roller, the mentioned heat-inlet section is then used as a radiation device to release the heat from the roller body (3). <IMAGE>
