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 ##STR1## wherein x is from 10 to 90 mole %, y is from 10 to 90 mole %, x+y equal 100 mole %, and OR.sub.f 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.

This application is a Continuation-In-Part of application Ser. No. 09/501.459, filed Feb. 10, 2000 for FLUOROCARBON RANDOM COPOLYMER FOR USE IN EXTERNALLY HEATED ROLLER now abandoned, and further is related to application Ser. No. 09/500,826, filed Feb. 10, 2000 for EXTERNALLY HEATED EXTERNAL HEATER ROLLERS, the disclosure of which is incorporated herein by reference now U.S. Pat. No. 6,304,740.
An electrophotographic photoreceptor is disclosed which is provided with an anti-corrosion layer on the interface between the substrate surface and hole blocking layer. The photoreceptor has high mechanical strength and minimizes defects in print for longer periods of time.
