Abstract
The invention provides an elastic roller for use in an apparatus for fixing a toner image, electrostatically formed on copy paper by passing the toner image between two rollers, comprising a roller core, a fusible fluororesin layer coated on the outside of the roller core, a porous fluororesin having porous portions affixed to the roller core through the fusible fluororesin layer, and a rubber impregnated into the porous portions of the porous fluororesin. It also provides a method for making an elastic roller including the steps of fusing a fusible fluororesin layer on the outside of a roller core or base; affixing a porous fluororesin having porous portions to the roller core through the fused fluororesin layer; filling the porous portions of the porous fluororesin with a rubber after fusing the porous fluororesin to the roller core; and hardening the rubber.
