Abstract

PURPOSE:To shorten the rising time of temperature by forming the main body of a heat roller, having a heater internally, by using a material having excellent heat conduction characteristics by the powder metallurgical method. CONSTITUTION:A heat fixing roller 1 and a press roller 2 are contacted under pressure each other, and turn as shown by arrows A and B. The heat fixing roller 1 consists of a cylindrical roller body 3 and a bar heater 4 arranged on the center shaft of the body 3. When a copying form 5 having adsorbed toner 6 is inserted between the rollers 1 and 2, the copying form 5 is heated by the rollers 1 and 2, and moves forth between the rollers 1 and 2 to deposit the toner 6 on the copying form 5 during the period. To form the cylindrical roller body 3 of the heat fixing roller 1, a mixture of aluminum powder and copper powder is molded under pressure and sintered. Namely, a product by the powder metallurgical method is used.
