Fixing apparatus providing a fixing apparatus capable of suppressing a temperature rise in a non-sheet-passing portion without degrading first print out time

摘要

A fixing apparatus includes a thermal conductive member that is in contact with a heater and has a thermal conductivity higher than the thermal conductivity of a base material of the heater, and a thermal-resistant member that is disposed between the thermal conductive member and a support member configured to support the heater, a thermal resistance in a thickness direction of the thermal-resistant member being higher than the thermal resistance in the thickness direction of the thermal conductive member.
