Abstract: 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.
