Abstract:
A deformable toner fuser roller, for use in a fusing station of an electrostatographic machine comprising:a rigid cylindrical core member; an overdrive-controlling, elastically deformable structure surrounding the core member having a base cushion layer formed on the core member, an optional barrier layer adhered to the base cushion layer; and a toner release layer adhered to the barrier layer wherein the base cushion layer comprises a foam having a Poisson's ratio between 0.2 and 0.4, and the toner release layer has a Poisson's ratio greater than 0.4; and wherein the fuser roller is adapted to be heated by a heat source external to the roller and the overdrive-controlling elastically deformable structure comprises an effective or operational Poisson's ratio between 0.2 and 0.4.
