ABSTRACT:
Offset of toner powder upon a heated surface is prevented by applying an emulsion of a high viscosity release agent and a low viscosity dispersion liquid upon the heated surface by an applicator means in contact with the heated surface. The preferred emulsion is a mixture of high viscosity silicone oil and water. There is also described a method of manufacturing a fibrous applicator and the article formed thereby which includes the impregnation of the fibrous applicator with an emulsion of high viscosity liquid and a low viscosity dispersion liquid and the removal of low viscosity dispersion liquid after impregnation with the emulsion is complete. A preferred applicator is a fibrous wick having water removed therefrom after the fibrous wick is impregnated with an emulsion of a polydimethylsiloxane liquid and water.
