Trennmittel-Spenderelement mit interpenetrierendem Fluorsilikon-Netzwerk

摘要

A release agent donor member (50) for a toner fixing system, the donor member contains, in order: a base member; an optional intermediate layer; an outermost layer comprising a polymeric composition containing a cured interpenetrating network of fluorocarbon elastomer and one or more silicone resins selected from a polyfunctional poly(C(1-6)alkyl)siloxane polymer; a polyfunctional poly(C(1-6) alkyl)arylsiloxane polymer; and combinations thereof; and a release agent (33) whereby interchange of siloxane oil with the siloxane in the silicone rubber network is reduced and excessive swelling of the donor member prevented.
