Abstract

Fuser apparatus 15 for fixing toner images 44 to sub-~ strates 42 comprising a heated fuser roll structure 30 and a backup roll structure 38 forming a nip 40 through which said substrates pass, with the toner images con~ tacting the heated fuser roll structure to thereby soften the toner images. The heated fuser roil structure is characterized by the provision of an outer layer 34 of Teflon material to which a release agent such as silicone oil 54 is applied. A release agent applica~ tor in the form of a web 56 for coating the fuser roll structure is provided and comprises an outer surface having a higher affinity for toner than does the surface of the Teflon coated fuser roll struc~- ture with the silicone oil thereon. The web is

supported such that it contacts the fuser roll structure
and such that it can be moved through a sump 50 contain~
ing release agent material 54 which is to be applied to
the surface of the fuser roll structure. The web is so
supported that it can be moved by the fuser roll struc-
ture when the relative friction therebetween is at a
sufficiently high level and such that relative slippage
therebetween occurs when a fresh supply of release
agent material is presented thereto by...
