To provide a fixing roller whose rising time up to a fixing temp. is shortened and power consumption is reduced by patterning a resistance heating element layer on a sputtering method and providing the resistance heating element layer on a cylindrical substrate and further, a layer for enhancing the peelability of toner on the heating element layer.
The resistance heating element layer 2 is patterned on the sputtering method as a low-temperature film forming method, without destroying the cylindrical substrate 1, to be provided thereon. Electrode layers 3 are provided on both ends of the heating element layer 2 by the sputtering method and the layer 4 having the peelability of the toner, (preferably, a 'Teflon (R)' layer, a perfluoroalkoxy resin layer, etc.,) is provided to cover a part of the electrode layers 3 and the heating element layer 2 by a powder coating method, a tube coating film method, etc. The cylindrical substrate 1 is made of aluminium, stainless steel or heat-resistant plastic. Thus, the rising time up to a prescribed fixing temp. can be shorten, the distribution of a temp. can be made uniform and the power consumption can be reduced.
