Abstract
PURPOSE:To prevent an offset phenomenon generated at the low temperature in a heat roller by passing a copying sheet in which toner pictures have been formed through a pressure roller and then passing it through a heated heat roller to fix the sheet. CONSTITUTION:A copying sheet 2 holding powder toner pictures 1 passes through two unheated metallic pressure rollers 31 and 32. The copying sheet 2 passes through a metallic heat roller 5 heated from its inside by an infrared-ray lamp 4 and backup roller 6 composed of silicone rubber while being heated and pressed to fix powder toner pictures on the copying sheet 2. Since the toner pictures 1 are completely packed and smoothed before they are inserted into the heat roller 5, the offset phenomenon can be prevented even if the surface temperature of the heat roller is comparatively low.
