Abstract:
In a heat roller of a fixing apparatus according to an embodiment of the present invention, a sleeve is slidable with respect to a supporting roller. Flanges that regulate the sleeve have smooth surfaces, are arranged at gaps apart from a foamed rubber layer of the supporting roller, and freely rotate with respect to the supporting roller. Edges at both ends of the foamed rubber layer of the supporting roller are formed in an R shape and set shorter than the length of a body of the press roller. The sleeve has markings for detecting a state of the heat roller.
