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.
A method for preventing the offset of toner powder to a heated surface used to fix the toner powder to a substrate when the substrate is in pressure engagement with the heated surface comprising applying to the heated surface a high viscosity release agent liquid by continuously replenishable applicator means in contact with the heated surface, said applicator means in contact with a reservoir of a low viscosity emulsion of the high viscosity release agent and an inert vaporizable dispersion liquid for supplying and transporting said high viscosity release agent liquid to the heated surface.
A device for heat fusing toner powder to a substrate by containing the toner powder with a heated surface comprising:
An article comprising a heat resistant, fibrous applicator for the contact application of fluid upon the surface of a heated member, said fibrous applicator being impregnated with an emulsion of a high viscosity liquid and a dispersion liquid and thereafter reduced of dispersion liquid.
