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.

A resistance heating element includes a positive temperature coefficient resistance heating layer having a positive temperature coefficient, and a negative temperature coefficient resistance heating layer, which is connected to the positive temperature coefficient resistance heating layer and has a negative temperature coefficient.
Abstract:
A solder composite is provided. The solder composite may include: a metal-based solder matrix, a capsule dispersed in the solder matrix, and a self-healing material that is encapsulated in the capsule. The self-healing material may be configured to react with the solder matrix when in contact with the solder matrix such that at least one of an electrically conductive intermetallic compound and an electrically conductive alloy is formed.
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%.

A nano composite with superhydrophobic surfaces including a bulk portion and a surface portion having a superhydrophobic pattern, wherein the bulk portion and the surface portion include the same material, and methods of manufacturing of the nano composite.
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.
