Abstract:
A fixing device included in an image forming apparatus includes a fixing rotary body, a heater disposed opposite the fixing rotary body, an opposed body contacting an outer circumferential surface of the fixing rotary body, a reflector disposed opposite the heater, and a heat shield disposed between the heater and the fixing rotary body and includes a shield portion to shield heat radiated from the heater to the fixing rotary body. Heat reflectance of at least a surface of the shield portion where the heat shield faces the heater is set to a value smaller than heat reflectance on a surface of the reflector opposite and facing the heater. Also, heat absorptance of at least a surface of the shield portion where the heat shield faces the heater is set to a value greater than heat absorptance on a surface of the reflector opposite and facing the heater.
