    摘要： 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.

    摘要： In an electrostatic copying apparatus of the type in which a magnetic toner is applied to an image holder such as a drum from a developing roller which in turn receives the toner from a supply roller, a source of relative positive and negative voltages is alternately applied to the developing roller. This produces electric fields which move the toner from the supply roller to the developing roller and then to the image holder with the desired relative polarities.
