1. An image forming apparatus comprising:

  • a plurality of image forming units configured to respectively form an image;

    a plurality of voltage generation units configured to respectively generate voltages for driving the plurality of image forming units,wherein each of the plurality of voltage generation units comprises;

    a voltage generator having a transformer, configured to generate a voltage by a switching operation that is driven by changing an input voltage of primary side of the transformer;

    a clock generation unit configured to generate a clock signal of a frequency that becomes a reference frequency of the switching operation; and

    a setting unit configured to set the frequency of the clock signal that the clock generation unit generates,wherein the setting units of the plurality of voltage generation units set the frequencies of the respective clock signals so that the frequencies of the clock signals that the plurality the clock generation units generate are different from each other.
