PROBLEM TO BE SOLVED: To provide a fixing device that has excellent practicality and high reliability by obtaining, at high production efficiency, an induction coil that saves more energy during heat generation of a heat roller. SOLUTION: A coil guide 137 in the form of a helical groove is formed on the outer circumferential face of a bobbin 117. A winding wire 116 is wound along the coil guide 137 on the bobbin 117. Thus, a coil unit 119 having a coil 118 of a specified number of loops is always obtained. COPYRIGHT: (C)2005,JPO&NCIPI
