Summary:The present general inventive concept describes a switching mode power supply (SMPS) and a method of supplying power by using the same. An SMPS that may be used in an image forming apparatus can include a transformation unit to transform an alternating-current (AC) voltage input to the SMPS, into at least one direct-current (DC) voltage by using a transformer, a first output voltage output unit to output the transformed DC voltage as a first output voltage of the SMPS, a first switching unit to prevent output of the second output voltage, and a second switching unit to prevent output of the second output voltage.
