摘要： A fixing unit includes a heating roller having a heating part, and a pressing roller disposed corresponding to the heating roller. A frame surrounds the heating and pressing rollers and allows a recording medium to pass between the rollers. The frame is mounted with a heat reflective layer on an inner surface thereof. An adiabatic layer may be disposed between the heat reflective layer and the frame. The heat reflective layer may be provided only proximal both sides of the frame when using an adiabatic layer. Accordingly, the initial heating time of the fixing unit, heat loss, and power consumption may be reduced.

摘要： A liquid toner composition and a preparation method utilize a colorant, an organosol, a charge control agent, a carrier liquid, a dispersion assistant agent, and a photoreactive catalyst, in which the dispersion assistant agent is a polymer including an unsaturated functional group to cause photopolymerization in a presence of the photoreactive catalyst, and the photoreactive catalyst produces a free radical through an irradiation of light, and initiates the photopolymerization of the dispersion assistant agent. According to embodiments of the present invention, the toner organosol rarely affects the physical properties required of the liquid toner, and an offset error in a fixing operation is removed, resulting in an improved quality of a printed image.

摘要： A liquid toner for electrophotography and a method of preparing the liquid toner are disclosed. The liquid toner includes a carrier liquid, an organosol, a colorant, a charge controlling agent (CCA), and (meth)acrylic (co)polymer soluble in the carrier liquid. The liquid toner has a low solidification rate and good redispersion when left for a long period of time, especially at a high temperature for a long period of time, while maintaining the existing physical properties of a liquid toner, such as image density, at certain levels.
