Provided is a two-component developer with which degradation of development is inhibited even in the case of prolonged use, and thereby a high quality image exhibiting high resolution and sufficient image density can be formed for a long duration. The power converter module includes a reference voltage generation unit, a voltage loop control unit, a current loop control unit, an input voltage compensation unit, and a pulse width modulation generation unit, to transfer input power to stable output power for providing power to an external loading device through driving bridge switch unit with external driver. The breaking means comprises a laser oscillator, a reflection mirror and a focusing lens. An integrated circuit is electrically coupled to the antenna pattern.
