Title:
Fixing device
Document Type and Number:
Japanese Patent JP6270458
Kind Code:
B2
Abstract:
An image heating apparatus configured to heat an image formed on a recording material includes a cylindrical rotatable member including a conductive layer, a magnetic core inserted through the rotatable member, a coil helically wound around an outer side of the magnetic core within the rotatable member, and an inverter configured to supply an alternating current to the coil. A frequency of the alternating current supplied from the inverter is within a range of 20.5 to 100 kHz. The conductive layer generates heat by electromagnetic induction due to an alternating magnetic field produced from the alternating current supplied to the coil. The coil is wound at an interval of 1 mm or longer.
