    • An electronic device includes a supply circuit board having a switching power supply circuit for outputting DC voltages in conformity with a type of commercial power, and a control circuit, which is connected to the supply circuit board, for performing control in accordance with the type of the commercial power. The control circuit discriminates the type of commercial power based upon a voltage value that is the result of dividing a DC voltage by the supply circuit board, and changes over control of a fixing heater in dependence upon the type of commercial power discriminated. When the door of an image forming apparatus is opened, the supply circuit board halts the supply of DC to a high-voltage circuit, thereby suppressing the generation of high voltage, and the control circuit is notified of the fact that the door has been opened.

    • The image forming apparatus is provided with a driving circuit board for driving an apparatus main body, a control circuit board for controlling the apparatus main body, and an image controller board for controlling image data, in which the driving circuit substrate and the image controller board are arranged substantially vertically, and the control circuit board is arranged substantially horizontally. Consequently, a high-frequency wiring part can be shortened, and reduction of radiation field noises and costs for coping with the noises can be realized. Moreover, since heat radiation efficiency increases, deterioration of components and degradation of an image quality due to increase in temperature inside the apparatus can be prevented.
    • 图像形成装置设置有用于驱动装置主体的驱动电路板,用于控制装置主体的控制电路板和用于控制图像数据的图像控制器板,其中驱动电路基板和图像控制器板 基本上垂直布置,并且控制电路板基本上水平布置。 因此,可以缩短高频布线部分,并且可以实现辐射场噪声的减小和用于应对噪声的成本。 此外,由于散热效率提高,因此能够防止由于设备内部的温度升高导致的部件劣化和图像质量的劣化。
