FUSING UNIT AND IMAGE FORMING DEVICE COMPRISING THE FUSING UNIT

摘要

PURPOSE: A fusing unit and a device forming an image including the same are provided to increase thermal efficiency of the fusing unit by heating the surface of a pressurization unit from the outside. CONSTITUTION: Heating source(110) radiates heat for performing a fusing operation. A pressurization unit(120) is parallelly arranged to the heating unit and applies a pressure in order to perform the fusing operation. A heating unit(130) heats the surface of the pressurization unit. A difference between the surface of the pressurization unit and the heating source satisfies a specific regression equation.
