Abstract
A fixing device includes a magnetic-field generating unit that generates a magnetic field; a substantially cylindrical fixing rotational body that faces the magnetic-field generating unit, generates heat by electromagnetic induction of the magnetic field, and melts and fixes a developer image to a recording medium; a temperature-sensitive contact part that contacts an inner side of the fixing rotational body, and faces the magnetic-field generating unit, its permeability decreasing if its temperature becomes a permeability-change start temperature or higher; and a temperature-sensitive non-contact part arranged at the inner side of the fixing rotational body to face the magnetic-field generating unit in a range different from the contact part, and spaced from the fixing rotational body. An angle defined by the contact part and the center of the fixing rotational body is 60° or larger.
