Abstract:
A fusing apparatus including a heating unit including a heater having a substantially flat shape; a nip forming unit which faces the heating unit and forms a fusing nip with the heating unit; and a driving unit which moves the heating unit to alternately repeat a forward motion whereby the heating unit moves forward in a moving direction of the recording medium, when the fusing nip is formed, and a returning motion whereby the heating unit moves backward in a direction opposite to the moving direction of the recording medium, when the fusing nip is released.
Abstract:
A heating member for a fusing apparatus includes a resistive heating layer including a base polymer and an electroconductive filler dispersed in the base polymer, where the resistive heating layer generates heat by receiving electric energy, and where a storage modulus of the resistive heating layer is about 1.0 megapascal or greater.
Abstract:
A heating member includes: a resistive heating layer which generates heat when supplied with electrical energy; a release layer as an outermost layer of the heating member and including a polymer; an intermediate layer disposed between the resistive heating layer and the release layer. The resistive heating layer includes a base polymer, and an electroconductive filler dispersed in the base polymer. The intermediate layer includes a polymer material being a same type as the base polymer of the resistive heating layer or the polymer of the release layer.
Abstract:
A method of forming a thin film resistive heating layer, the method including: forming a polymer layer by extruding a polymer paste, in which an electrically conductive filler is dispersed, by using an extrusion molding operation, on an outer circumferential surface of a cylindrical member; and forming a thin film resistive heating layer by making an outer diameter of the polymer layer uniform by using a ring blading operation.
Abstract:
A heating member includes: a resistive heating layer including: a medium-passing area, and non-medium-passing areas respectively on opposing sides of the medium-passing area at opposing side portions of the resistive heating layer; a core which supports the resistive heating layer; a thermally conductive layer between the resistive heating layer and the core, and disposed in a non-medium passing area at a side portion of the resistive heating layer; and an electrode which is between the resistive heating layer and the core, contacts the side portion of the resistive heating layer and supplies current to the resistive heating layer. A ratio of a contact area between the thermally conductive layer and the resistive heating layer to an area of the non-medium-passing area in which the thermally conductive layer is disposed, ranges from about 5% to about 25%.
