    • A fusing apparatus for fusing toner images on a receiver medium. The fusing apparatus includes a fuser member having a contact surface and a pressure member having a contact surface. The pressure member is positioned adjacent the fuser member for forming a nip therebetween to receive the receiver medium. The pressure member controllably exerts pressure on the fuser member and the receiver medium. A first heater member has a contact surface and is positioned adjacent the fuser member and external thereto, the surface of the heater member contacting the surface of the fuser member to transfer heat to the fuser member. The fuser member heats the toner image on the receiver medium thereby fusing the toner image to the receiver medium. A first radiant heat assembly is positioned externally of the first heater member for controllably heating the contact surface of the first heater member.
    • 一种用于将调色剂图像定影在接收介质上的定影装置。 定影装置包括具有接触表面的定影器构件和具有接触表面的压力构件。 压力构件定位成邻近定影器构件以在其间形成间隙以接收接收器介质。 压力构件可控制地对定影器构件和接收器介质施加压力。 第一加热器构件具有接触表面并且定位成邻近定影器构件并且在其外部,加热器构件的表面接触定影器构件的表面以将热量传递到定影器构件。 定影器构件加热接收介质上的调色剂图像,从而将调色剂图像定影到接收介质。 第一辐射热组件位于第一加热器构件的外部,用于可控地加热第一加热器构件的接触表面。
