Patent number: 10216129Abstract: Exemplary embodiments provide a fuser member containing an intermediate layer and methods for forming the intermediate layer and the fuser member. In one embodiment, the fuser member can include a substrate, a resilient layer, a surface layer and an intermediate layer disposed between the resilient layer (e.g., a silicone rubber layer) and the surface layer (e.g., a fluoroplastic of PFA or PTEE). The intermediate layer can include a CNT/polymer composite containing a plurality of carbon nanotubes in a polymer matrix. The surface layer and the fuser member can thus be treated at a temperature of about 250° C. or higher.Type: GrantFiled: January 29, 2009Date of Patent: February 26, 2019Assignee: XEROX CORPORATIONInventors: Yu Qi, Nan-Xing Hu, David J. Gervasi, David C. Irving, Patrick J. Finn

Patent number: 8097339Abstract: A method of forming and a resulting selectively polished fuser member. The method includes selectively polishing that portion of the fuser member surface not subject to rapid natural wear. The method further includes polishing both a surface region subject to rapid sheet edge wear and a surface region not subject to rapid sheet edge wear, and polishing the surface region not subject to rapid sheet edge wear more than the surface region subject to rapid sheet edge wear. The rapid natural wear corresponds to sheet edge wear on the fuser member surface.Type: GrantFiled: June 24, 2008Date of Patent: January 17, 2012Assignee: Xerox CorporationInventors: Daniel L. Coughlin, Jr., Patrick J. Finn
