Patent ID: 8559861

Claim:
A fixing device comprising: a fixing belt including a hollow opening to define an inner surface to receive heat and outer surface to transmit the heat to a print medium; a pressing unit to apply a pressure on the print medium; a heating unit disposed within the hollow opening of the fixing belt to generate the heat; a nip plate disposed within the fixing belt to face the pressing unit, thus to form a fixing nip; a support element to support the nip plate; a reinforcement frame to reinforce a stiffness of the support element; and a reflection unit disposed within the fixing belt to reflect the heat radiated toward the support element from the heating unit, the reflection unit formed to reflect the heat toward the inner surface of the fixing belt and to block the heat from going toward the nip plate, wherein the reflection unit is connected with the nip plate to conduct the heat from the reflection unit to the nip plate, and the heating unit is disposed between the fixing belt and the reflection unit.
