Abstract:
A fixing device for fixing toner maintained on a recording sheet by heating and fusing the toner to the recording sheet, comprising:a rotatable heating member heated by a heat source;a rotatable pressure member for pressing against said rotatable heating member;a heat-moving member formed of material having excellent thermal conductivity characteristics and constructed so as to freely make contact with at least one rotatable member among said rotatable heating member and said rotatable pressure member; anda drive means to move said heat-moving member between a contact position and a retracted position relative to said at least one rotatable member,said heat-moving member changing one of heat capacity and thermal conductivity relative to an axial direction of one of said rotatable heating member and said rotatable pressure member, said heat-moving member having different heat absorption capability characteristics along a longitudinal axis thereof.
