PROBLEM TO BE SOLVED: To provide a power source device capable of suppressing fluctuation of output voltage associated with fluctuation of a load of load equipment, and an image forming apparatus including the power source device.SOLUTION: When a compound machine X is in a power saving mode, upon input of a print job to a NIC 18, a reception signal indicating the input is input to a control IC 41. At that time, the control IC 41 changes a PWM signal in a low frequency f1 to a PWM signal in a high frequency f2 before load fluctuation, and increases the amount of output. After that, the operation mode is changed to a normal operation mode. |
