Patent number: 4514486Abstract: In a method for the formation of images such as an electrophotographic method in which toners are used, when a heat roller is used for fixing toner images, the durability and the heat efficiency of the heat roller is improved reducing the wall thickness of the cylindrical metal of the heat roller, shortening the warming-up time, using a material having a substantial Young's modulus, and by shortening the outer diameter of the cylindrical metal, respectively.With respect to toners specifically used for the above, stains on an image carrier are prevented by making use of a binder that is fused at a heating temperature of the heat-fixing roller and is increased in the elasticity of the toner at the same temperature or higher. Such binders may be obtained by copolymerizing a polyhydric alcohol and/or a polyhydric amine, and a polyhydric carboxylic acid.Type: GrantFiled: August 26, 1983Date of Patent: April 30, 1985Assignee: Konishiroku Photo Industry Co., Ltd.Inventors: Meizo Shirose, Kunio Ito, Hiroyuki Takagiwa, Jiro Takahashi, Kouichi Gunzi
