| Zusammenfassung: | A fixing device includes a heated body of a hollow cylindrical shape that is made of a conductive material and driven to rotate about an axis center, and a coil that heats the heated body by means of induction heating. The coil is formed of plural coil elements divided in an axial direction of the coil parallel to a rotational axis direction of the heated body, and the coil elements are aligned in such a manner that directions of magnetic fields of adjacent coil elements are opposite to each other. The heated body is set stationary in the rotational axis direction and the coil is reciprocally driven in the axial direction. |
