A method of protecting a toner image on a resin-containing material surface comprising applying to the surface carrying the toner image a liquid fixing composition in which the liquid is a hydrocarbon liquid being mainly composed of (a) liquid aliphatic hydrocarbon(s) and which contains in dissolved form a film-forming copolymer composed of: (A) monomers, of the group consisting of C1-C5 aliphatic esters of methacrylic acid and vinyltoluene, (B) monomers of the group consisting of C7-C24 aliphatic esters of methacrylic acid or acrylic acid and optionally (C) monomers of the group consisting of C1-C5 aliphatic esters of acrylic acid and vinyl esters of C1-C10 aliphatic acids.
