  • Patent number: 10663919
    Abstract: In an image forming apparatus, if a path for transferring heat generated by a drive integrated circuit to a frame (a heat dissipation plate) of an apparatus main body has a point that divides the path, foreign matter such as dirt and dust can be caught at the point, so that heat dissipation efficiency can decrease due to presence of such foreign matter. Therefore, a configuration is provided in which a drive integrated circuit and a frame (a heat dissipation plate) provided in a cover are connected by a heat transfer member, so that a heat transfer path from the drive integrated circuit to the frame has no point that divides the path.
