Abstract
An image fixing apparatus stably maintains high efficiency in heat generation and reduces excessive heat and loss of electric power consumption for fixing image. In at least one embodiment, the image fixing apparatus includes a magnetic flux generating member to generate a magnetic flux, and a heat member to generate heat with the magnetic flux. The heat member includes a first heat layer and a second heat layer having a relatively higher volume resistivity than the first heat layer, and having different thickness and/or different volume resistivity depending on a position in the width direction of the second heat layer. Portions of the magnetic flux generating member face different sides of the heat member.
