Roller assembly containing externally heated roller with cured fluorocarbon random copolymer overcoat and fuser apparatus containing same
A heater roller assembly for use with a fuser apparatus includes a housing comprising a radiation shield enclosing a radiant heat source, and a heater roller that is disposed within the housing and is externally heated by the radiant heat source. The heater roller includes a core, a base cushion layer overlying the core, and an outer layer overlying the base cushion layer. The outer layer of the heater roller includes a fluorocarbon random copolymer having subunits of wherein x is from 10 to 90 mole %, y is from 10 to 90 mole %, x+y equal 100 mole %, and ORf is a perfluoroalkoxy group. A fuser apparatus includes a fuser roller whose outer surface is in contact with the outer layer of a heater roller included in a heater roller assembly.
