摘要： 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.

摘要： 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.
