  • Heating member using carbon nanotube and fixing unit using the heating member
    Patent number: 8290418
    Abstract: A fixing unit includes a heating member which includes a core member, and a heating layer. The heating layer is disposed on an outer circumference of the core member. The heating layer includes an elastic material, and carbon nanotube doped with metal and distributed in the elastic material as a conductive filler of the heating layer. A press member faces the heating member to form a fixing nip. The fixing unit applies heat and pressure to toner on a medium passing through the fixing nip, to fix the toner on the medium.
