Patent ID: 8078073

Claim:
A fixing apparatus comprising: a heat generating member configured to have a metal conductive layer; an opposite member configured to form a nip between the heat generating member and the opposite member; a contact and separation mechanism configured to contact and separate the heat generating member to and from the opposite member; an induction current generating coil disposed around the heat generating member; a drive source configured to rotate the heat generating member forwardly and reversely; a temperature sensor disposed downstream from the nip of the heat generating member and upstream from the induction current generating coil of the heat generating member at a time of forward rotation of the heat generating member; and a power controller configured to control a power of the induction current generating coil, and based on the direction of rotation of the heat generating member to apply a prescribed power to the induction current generating coil, the power controller applies a lower power to the induction current generating coil at the time of reverse rotation of the heat generating member compared with a power applied at the time of forward rotation of the heat generating member.
