Abstract:
A control unit of an image forming apparatus controls, in an image forming mode, a potential difference obtained by subtracting the voltage applied to the developer bearing member from the voltage applied to the regulating member so that the potential difference is set to the polarity of the developer, and the control unit controls, in a lubricant discharge mode, the potential difference obtained by subtracting the voltage applied to the developer bearing member from the voltage applied to the regulating member so that the potential difference is set to the polarity of the lubricant or “0”.
