ABSTRACT:
The fixing device includes: a fixing member including a conductive layer and fixing toner on a recording medium by electromagnetic induction; a magnetic-field generating member generating an alternate-current magnetic field intersecting with the conductive layer; a magnetic-path forming member that includes a circular arc facing the magnetic-field generating member, that forms a magnetic path of the alternate-current magnetic field, within a range up to a permeability change start temperature, and that allows the alternate-current magnetic field to go through the magnetic-path forming member within a range exceeding the permeability change start temperature; and a support member supporting the magnetic-path forming member. The circular arc shaped portion has an upstream edge in a moving direction of the fixing member and a position of the upstream edge is concaved toward a center of the magnetic path forming member from each of ends of the magnetic path forming member in a longitudinal direction.
