    • A development device includes a developing gap detection function. The development device also includes an organic photoconductive body, a developer conveying body, a DC power supply, an AC power supply, a discharge start voltage detection portion, and a controller. The discharge start voltage detection portion detects a discharge start voltage occurring between the developer conveying body and the organic photoconductive body when a voltage is supplied from the power supply unit in increments at predetermined intervals. The controller obtains a developing gap between the organic photoconductive body and the developer conveying body based on the discharge start voltage detected by the discharge start voltage detection portion, and outputs a developing voltage suitable for the obtained developing gap. Accordingly, the development device having the developing gap detection function detects the developing gap easily and accurately by recognizing the discharge start voltage, and improves image quality by regulating an image forming condition.
    • 显影装置包括显影间隙检测功能。 显影装置还包括有机光电导体,显影剂输送体,直流电源,交流电源,放电启动电压检测部和控制器。 放电开始电压检测部分以预定间隔增量从电源单元提供电压时,检测在显影剂输送体和有机光电导体之间产生的放电开始电压。 控制器基于由放电开始电压检测部分检测的放电开始电压获得有机光电导体和显影剂输送体之间的显影间隙,并输出适合于所获得的显影间隙的显影电压。 因此,具有显影间隙检测功能的显影装置通过识别放电开始电压来容易且精确地检测显影间隙,并且通过调节图像形成条件来提高图像质量。
