SELF-HEAT-GENERATING FIXING ROLLER

摘要

An object is to provide a self-heat-generating fixing roller that has a simple structure and good durability and that can be easily produced. A self-heat-generating fixing roller according to an embodiment of the present invention includes a columnar core bar, a heat-insulating layer stacked on an outer circumferential side of the core bar, a heat-generating layer stacked on an outer circumferential side of the heat-insulating layer and heated by supplying electricity, and a mold-releasing layer stacked on an outer circumferential side of the heat-generating layer. The heat-insulating layer preferably contains a matrix containing a synthetic resin or rubber as a main component, and a plurality of pores contained in the matrix. The heat-generating layer preferably contains a matrix containing a synthetic resin or rubber as a main component, and a plurality of electrically conductive fillers contained in the matrix.
