Abstract
A release agent for removing offset toner particles from the surface of a fixing roller of an electrophotographic copying machine comprises a dimethyl silicone oil, as a principal agent and contains polypropylene in the amount of about 1 weight % or less. The compatibility between the toner particles and the polypropylene is so small that the offset toner particles are easily separated from the silicone oil. The toner particles are preferably made of acrylic-styrene resin epoxy resin, or the like, or mixture thereof.
