Publication number: 20020136573Abstract: A method of curing a fuser member suitable for use in an image forming system using a radiant energy source. The fuser member comprises a substrate, a silicone rubber coating and a cross-linkable fluoroelastomer outer coating. The radiant energy source emits infrared energy directed towards the fluoroelastomer outer coating of the fuser member. The flouroelastomer coating is cured using infrared energy directed at specific bonds within the fluoroelastomer layer, so as to form directly with the infrared heat a cross-linked fluoroelastomer coating.Type: ApplicationFiled: January 25, 2001Publication date: September 26, 2002Applicant: Xerox CorporationInventors: Elizabeth L. Ogren, Carla M. Santos, Alan R. Kuntz, George A. Riehle, Laurence J. Lynd
