Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an image forming apparatus capable of reducing radiation noise.SOLUTION: An image forming apparatus 1 includes: an ASIC10 for performing information processing related to image formation; a switching regulator SR11 to/from which an input voltage VD is input and a voltage V1 lower than the input voltage VD is output; switching regulators SR21, SR22 to/from which the voltage V1 is input and voltages V2 and V3 lower than the voltage V1 are output. The voltages V2 and V3 are input to the ASIC10. The switching frequency f1 of the switching regulator SR11 is lower than the switching frequency f2 of the switching regulators SR21 and SR22.
