Abstract: A motor driving device is disclosed. The motor driving device includes: a rectifier rectifying alternating current (AC) power into direct current (DC) power to output an input voltage; a first buck-boost converter including a plurality of switches for converting the input voltage and having a buck mode of stepping down the input voltage and a boost mode of stepping up the input voltage; an inverter converting a DC-link voltage transformed from the first buck-boost converter into an AC voltage and transferring the AC voltage to a motor; and a controller receiving motor information related to driving of the motor, comparing magnitudes of a desired DC-link voltage depending on the received motor information and the input voltage with each other, and performing a control to switch only any one of the plurality of switches so that the first buck-boost converter is operated in the buck mode or the boost mode.

Abstract: An induction heating type fusing device and an image forming apparatus including the fusing device. The fusing device includes a magnetic flux generator and a compressing roller outside a fusing belt, first and second fusing rollers and a nip guide inside the fusing belt. The compressing roller compresses against the first and second fusing rollers and the nip guide to form nips, while the fusing belt is disposed between the compressing roller and the first and second fusing rollers and the nip guide.

Abstract: A heating roller including a resistive heating layer and a fusing device including the heating roller. By separately disposing a plurality of electrodes in an axis direction of the heating roller, and by independently controlling each electrode, the heating roller may correspond to various papers having different sizes. Accordingly, the temperature of the heating roller may be stably controlled.
