Hot Roll Fuser

The external elastomer sleeve of a xerographic fuser's hot roll is provided with increased resistance to abrasion by limiting the particle size of its filler constituent to no more than one micron.

The polymers used for the external sleeve of a hot roll are selected for their low surface energy, high toner-release properties. Inorganic fillers are added to provide the needed mechanical and thermal properties. Oxide-type fillers are preferred. Silica is one example.

We have discovered that the use of silica filler of a particle size no greater than one micron greatly increases the hot roll's resistance to abrasion, as occurs, for example, when mechanical fingers ride on the hot roll's surface in order to assist in the release of the copy paper's leading edge from the hot roll.
