    Abstract: A fusing device having a structure which may improve fusing performance is provided. The fusing device includes a heating roller disposed to contact a surface of the recording medium to transfer heat thereto, an endless belt disposed to rotate together with the heating roller, and a pressing member to press an inner surface of the endless belt to allow a fusing nip to be formed between the heating roller and the endless belt.The heating roller includes a shaft formed in a cylindrical shape, a heat-generating layer disposed to surround the shaft and to generate heat to heat the recording medium passing through the fusing nip, an insulating layer disposed between the shaft and the heat-generating layer to electrically insulate the heat-generating layer and the shaft, and a release layer disposed to surround the heat-generating layer and adapted to prevent the recording medium passing through the fusing nip from sticking to the heating roller.

    Abstract: An image fixing device includes a heat source configured to generate heat, a fixing belt heated by the heat source and disposed to be rotatable, a rotational member disposed to be opposite to the fixing belt and to press a printing medium to the fixing belt, and a supporting member to support an inner circumferential surface of the fixing belt so as to form a fixing nip between the fixing belt and the rotational member and having a plurality of heat insulation grooves formed in a surface thereof so as to reduce thermal conductivity of the supporting member. By the configuration of the present general inventive concept, it is possible to prevent or minimize a heat loss of the fixing belt and thus to enhance image forming efficiency.
