Fixing device and image forming apparatus

摘要

A fixing device (19) for fixing a toner image on a recording medium by applying heat to the recording medium includes a magnetic flux generator (24) and a heat generating member (20; 60). The magnetic flux generator (24) generates a magnetic flux. The heat generating member (20; 60) opposes the magnetic flux generator. The heat generating member includes a heat generating layer (203; 603) for generating heat by the magnetic flux generated by the magnetic flux generator. The heat generating layer has an eddy current load, obtained by dividing a volume resistivity by a layer thickness, varying depending on a position in a width direction of the heat generating layer. The heat generating layer includes a magnetic layer (203a; 603a) having a Curie point in a range of from 100 degrees centigrade to 300 degrees centigrade.
