Abstract
A fixing device for use in a copying machine. The device has a heating roller, a pressure roller, and a separation pawl. The pawl has an end portion contacting the peripheral surface of the heating roller at a first point close to a second point where the pressure roller and the heating roller contact each other. The pawl separates a sheet, on which an image has been fixed, from the heating roller, and guides this sheet along a line tangent to the periphery of the heating roller and connected to the second point. The sheet is thus prevented from being deformed.
