摘要:
A fixing roller/fixing belt having an elastic layer and a surface layer formed on a substrate material in the enumerated order, wherein the surface layer is a layer formed by thermally shrinking a PFA tube, and the surface layer and the elastic layer are bonded together through a PFA-containing adhesive material. In particular, a fixing roller/fixing belt in which the ratio of heat shrinkage of the PFA tube forming the surface layer is 3 to 20%. Also, a fixing roller/fixing belt, in which the quantity of PFA contained in the PFA-containing adhesive material is 20 to 30 wt %.

A fluororesin-covered roller and a production method thereof. The fluororesin-covered roller has a laminar structure in which a rubber layer and a fluororesin layer are provided in this order on a roller base material. In the fluororesin-covered roller, the fluororesin layer is a covering layer formed of a fluororesin tube having a thickness of 10 μm or more and less than 20 μm.
摘要:
A pressure roller includes a rubber layer containing organic microballoons and a heat-resistant resin layer arranged in that order on a roller base, wherein an intermediate rubber layer having a heat conductivity of 1.0 to 4.0 W/m·K is arranged between the rubber layer containing the organic microballoons and the heat-resistant resin layer. There is provided a method for producing the pressure roller.
