摘要： A hot roll, for use in a xerographic, dry-release, hot roll fuser, is made by a method which adds iron-containing, magnetically permeable, particles to the elastomer as the elastomer is mixed. The particles may be pre-coated with a silane adhesive promoter. The mixed elastomer is then injected around a hollow, cylindrical aluminum core. As the elastomer sets up, in the mold, a magnetic field is applied such that the iron-containing particles migrate toward the metal core, and away from the exterior surface of the elastomer. This exterior surface will later be used to fuse xerographic toner. After the elastomer has set, its external surface is ground slightly, to produce a true circular-cylinder, but without exposing the underlying, more dense, layers of iron particle filler. As a result, the elastomer-to-core interface is mechanically strong, and yet the fusing property of the elastomer is not degraded by the presence of filler.
