    摘要： A fixing device includes a fixing rotary body rotatable in a predetermined direction of rotation to radiate infrared rays; a pressing rotary body, rotatable in a direction counter to the direction of rotation of the fixing rotary body, pressed against the fixing rotary body to form a fixing nip therebetween through which a recording medium bearing a toner image is conveyed; a heater disposed opposite the fixing rotary body to heat the fixing rotary body; a temperature detector spaced apart from the fixing rotary body to detect a temperature of the fixing rotary body based on the infrared rays from the fixing rotary body and disposed below the fixing nip in a vertical direction; and a tube disposed between the fixing rotary body and the temperature detector, the tube through which the infrared rays from the fixing rotary body enter the temperature detector.

    摘要： A fixing device includes a fixing rotary body, a heat shield movably disposed opposite the fixing rotary body, an opposed body contacting the fixing rotary body to form a nip therebetween through which a recording medium is conveyed, and a temperature detector to detect a temperature of at least one of the fixing rotary body and the opposed body. A controller, operatively connected to the heat shield and the temperature detector, determines a rotation angled position to which the heat shield is moved based on a size of the recording medium and the temperature of the at least one of the fixing rotary body and the opposed body detected by the temperature detector.

    摘要： A fixing device includes a rotatable fixing member; a heating source configured to heat the fixing member; an opposing member configured to come into contact with an outer circumferential surface of the fixing member to form a nip portion; and a shielding member configured to block heat from the heating source. The shielding member is configured to rotate about a position different from the center of the heating source so as to be movable between a shielding position and a retraction position. The shielding position is a position where the shielding member comes close to the heating source to block heat from the heating source to the fixing member. The retraction position being a position where the shielding member is retracted away from the shielding position.

    摘要： 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.
