IMAGE FORMING APPARATUS AND FIXING DEVICE

摘要

An image forming apparatus includes: a toner image forming unit; a transfer unit transferring a toner image onto a recording medium; and a fixing unit. The fixing unit includes: a fixing member fixing toner onto a recording medium with a conductive layer heated by electromagnetic induction; a pressure member coming into pressure contact with an outer peripheral surface of the fixing member, forming a fixing pressure portion between the pressure member and the fixing member; a magnetic field generating member generating an alternate-current magnetic field intersecting with the conductive layer; and a heat storage member contacting the fixing member and facing the magnetic field generating member with the fixing member interposed therebetween, the heat storage member generating heat to supply heat to the fixing member. The image forming apparatus further includes first and second power supplies respectively supplying power to the magnetic field generating member and the heat storage member.
