Abstract: A magnetic cooling apparatus including a plurality of magnetic regenerators including a plurality of magnetocaloric materials to emit heat when magnetized and to absorb heat when demagnetized. The magnetic regenerators are rotatably disposed on a circumference having a predetermined radius, at least one coil is disposed on the circumference and coupled to the magnetic regenerators, and a plurality of permanent magnets is provided inside and outside the circumference to generate a magnetic field to magnetize or demagnetize the magnetic regenerators. The at least one coil interacts with the magnetic field generated by the permanent magnets to rotate the magnetic regenerators. The coil interacting with the magnetic field to magnetize or demagnetize the magnetic regenerators is coupled to the magnetic regenerators such that the magnetic regenerators reciprocate or rotate, thereby minimizing a size of the magnetic cooling apparatus, relative to the use of a motor. In addition, a member to switch a channel of a heat transfer fluid directly performs heat transfer between the heat transfer fluid and an external fluid, thereby minimizing heat loss.

Abstract: A fusing unit and an image forming apparatus to form an image on a recording medium including a fusing unit are provided. The image forming apparatus includes a heating member having a surface divided into a plurality of heating regions and heating the recording medium, and a pressurizing member to apply pressure to the recording medium, the fusing unit fusing the image to the recording medium by applying heat and pressure to the recording medium, a driving unit to supply rotational force to the pressurizing member, and a power supply to supply power to the heating member and the driving unit, wherein the heating regions have different heating values per unit area. The image forming apparatus prevents overheating of a paper-contact heating region without idling the fusing unit in order to radiate heat accumulated in the paper-contact heating region.
