Abstract
Abstract A stainproofing oil for a heat fixing roller, which consists essentially of a fluorosilicone compound having a silicon atom to which a monovalent fluorine-containing group selected from the formulae (1) to (3) is bonded:Rf1-X1-(1)Rf2-X2-O-X3-(2)Rf3-X4-O-X5-(3)wherein Rf1 is a monovalent polyfluorohydrocarbon group, Rf2 is a monovalent polyfluoroalkyl group containing an ether oxygen atom, Rf3 is a monovalent polyfluorohydrocarbon group, and each of X1 to X5 independently is a bivalent hydrocarbon group.
