Abstract
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.
