Abstract
An electrophotographic fixing device which is fundamentally constructed by assembling a heat fusing roller made of a resilient material, a rigid press-contacting roller, and a heating roller, wherein the heat fusing roller is provided at a position to contact a copying material at the side thereof bearing a developed image, and has its surface heated by means of the heating roller, and wherein the copying material is pressed against the heat fusing roller by the press-contacting roller to complete the image fixing. The fixing device further includes means to apply an appropriate quantity of an image separating agent onto a front end part of a non-fixed reproduced image on the copying material, over a certain width, the device being provided at a position immediately preceding the fixing device and actuated by a timer.
