ABSTRACT:
An apparatus and a method for applying a releasing agent to a fixation roller so that toners are not undesirably built up on the rollers and unwanted spots on a document being reproduced are avoided. The releasing agent includes a polypropylene powder dispersed in silicone oil wherein the powder and oil are heated to raise the powder to a molten state and the powder and oil are then cooled forming fine particles of polypropylene powder that do not tend to float on the top of the silicone oil.
