<p>PROBLEM TO BE SOLVED: To prevent the erroneous operations of other electronic devices around an image forming apparatus.SOLUTION: When power is turned ON for an image forming apparatus, a mode setting part sets a first operation mode to operate a power supply circuit with a normal frequency (S11 and S12). Then, when a sensor part detects a human body to be present at a predetermined detection position before the image forming apparatus (YES in S13), the mode setting part switches the first operation mode to an erroneous operation prevention mode (S14) to operate the power supply circuit with an erroneous operation prevention frequency. When the sensor part detects no human body at the predetermined detection position (NO in S13), the mode setting part switches the erroneous operation prevention mode to the first operation mode to operate the power supply circuit with a normal frequency.</p> |
