    • A developing method for an electrostatic latent image comprises the steps of applying and retaining a layer of developer on a supporting sleeve, conveying the developer on the supporting sleeve to a development area, and regulating the quantity of the developer on the supporting sleeve by a developer regulating device before the developer is conveyed to the development area. The regulating step includes impressing a bias voltage so as to establish a field between the supporting sleeve and the regulating device in order to selectively retain developer on the supporting sleeve which has a desired polarity and quantity of charge for development. The developer regulating device may be a sleeve rotated in a direction opposite to the direction of rotation of the supporting sleeve, and has a bias voltage impressed thereon.
    • 一种用于静电潜像的显影方法包括以下步骤:在支撑套筒上施加和保持显影剂层,将支撑套筒上的显影剂输送到显影区域,以及通过显影剂调节支撑套筒上的显影剂的量 显影剂被传送到开发区之前的调节装置。 调节步骤包括施加偏置电压,以便在支撑套筒和调节装置之间建立一个场,以选择性地将显影剂保持在支撑套筒上,该支撑套筒具有期望的极性和充电量用于显影。 显影剂调节装置可以是在与支撑套筒的旋转方向相反的方向上旋转的套筒,并且具有施加在其上的偏置电压。
