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.

Abstract: A thermal roller for fixing a powdered toner image onto an image receiving sheet is provided with a sub-surface resistive heat generating layer adjacent the outer surface of the roller. The thickness of the heat generating layer or the materials that constitute the layer are controlled so that the resistance per unit length of the thermal roller increases gradually in the axial direction from the center portion thereof toward and to both ends. Electrical energy passed through the heat generating layer generates a desired temperature distribution profile along the roller to provide appropriate fixing temperatures, without excessively increasing the temperature at both ends of the roller.
