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.

Heating member using carbon nanotube and fixing unit using the heating member

A heating member includes a weight supporter having an outer circumference, and a resistive heating disposed on the outer circumference of the weight supporter. The resistive heating layer includes a conductive filler dispersed in a base material. A pair of electrodes extends along a length direction of a rotational axis of the weight supporter and is arranged along a circumference of the weight supporter for supplying electric power to the resistive heating layer.
