Abstract
A fixing apparatus includes a first rotary member, a heating element, a second rotary member, a nip member, a reflection member, and a support member. The support member configured to transit to a pressurized state and a non-pressurized state, the pressurized state being a state in which a first position and a second position of the support member are pressurized in a pressurization direction toward the second rotary member, the non-pressurized state being in which the pressurized state of the support member is released. The support member includes a contact surface in contact with the reflection member in the pressurized state. The contact surface takes such a posture that a center position between the first and second positions in the rotation axial direction is close to the second rotary member rather than the first and second positions in a case where the support member is in the non-pressurized state.
