PURPOSE:To increase the adherence strength of an internal elastic layer and a housing fluororesin layer, and to improve the durability by forming a constitution which has provided an intermediate resin film layer between the internal elastic layer and the housing fluororesin layer. CONSTITUTION:In case an elastic rotor has been utilized for heating and fixing a toner image in an electrophotographic copying device, a fixing device usually has a heating source H in the inside, and constituted of a fixing roller 1 for contacting an unfixed toner image T which has been carried on transfer paper P, and a pressure roller 10 for pressing the transfer paper P carrying the toner image, against the fixing roller 1. The fixing roller 1 and the pressure roller 10 have the same constitution, and consist of intermediate resin film layers 5, 15 and housing resin layers 6, 16 being mold release layers. In this way, the elastic rotor consists of a structure having the intermediate resin film layer between the elastic layer and the housing resin layer, therefore, a danger of peeling of the internal elastic layer and the housing resin layer is decreased remarkably, and also, the durability can be increased remarkably. |
