Abstract
A fixing device includes an endless, flexible fixing member, a heat conductive member, a heater, a pressing member, a nip formation member, and a radiation member. The endless, flexible fixing member is formed into a loop. The heat conductive member is disposed within the loop formed by the fixing member to conduct heat to the fixing member. The heater is disposed near the heat conductive member to heat the heat conductive member. The pressing member is rotatably pressed against the fixing member to form a fixing nip between the fixing member and the pressing member. A recording medium is conveyed through the fixing nip. The radiation member is detachably pressable against an outer circumference of the fixing member to contact the fixing member with the heat conductive member to cool the fixing member and the heat conductive member.
