    • A fixing device includes a heat conductor disposed opposite an inner circumferential surface of an endless belt to heat the endless belt. A nip formation pad is disposed opposite the inner circumferential surface of the endless belt and presses the endless belt against a pressing rotary body to form a fixing nip between the endless belt and the pressing rotary body through which a recording medium bearing a toner image is conveyed. A support is disposed opposite an inner circumferential surface of the heat conductor and contacts an abutment face of the nip formation pad to support the nip formation pad against pressure from the pressing rotary body. A heat insulator is interposed between the heater and the nip formation pad and the support to shield the nip formation pad and the support from the heater.
    • 定影装置包括与环形带的内周面相对设置的加热导体的加热导体。 压区形成垫与环形带的内圆周表面相对地设置,并将环形带压靠在压制旋转体上,以在环形带和压制旋转体之间形成定影辊隙,通过该压紧旋转体,承载调色剂图像的记录介质 。 支撑件布置成与导热体的内圆周表面相对并且接触压区形成垫的邻接表面以支撑压区形成垫抵抗来自压制旋转体的压力。 加热器和辊隙形成垫和支撑件之间插入绝热体,以将压区形成垫和支撑件从加热器屏蔽。

    • A fixing device includes a heat pipe, a fuser belt, a heater, a fuser pad, a pressure member, and a coupling mechanism. The heat pipe is formed of a sheet of metal bent into a generally cylindrical configuration with a pair of opposed longitudinal edges thereof spaced apart from each other to define a longitudinal slot therebetween. The fuser belt is looped for rotation around the heat pipe. The heater is disposed within the heat pipe to heat the heat pipe to conduct heat to the fuser belt. The fuser pad is accommodated in the longitudinal slot of the heat pipe inside the loop of the fuser belt. The pressure member is disposed parallel to the heat pipe with the fuser belt interposed between the fuser pad and the pressure member. The coupling mechanism includes a pair of first coupling portion and a pair of second coupling portions.
    • 固定装置包括热管,定影带,加热器,定影垫,压力构件和联接机构。 热管由弯曲成大致圆柱形构造的金属片形成,其一对相对的纵向边缘彼此间隔开,以在它们之间形成纵向槽。 定影带环绕热管旋转。 加热器设置在热管内以加热热管以将热量传导到定影带。 定影垫容纳在定影带环内的热管的纵向槽中。 压力构件平行于热管布置,定影带插入在定影垫和压力构件之间。 联接机构包括一对第一联接部和一对第二联接部。
