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： A development apparatus for developing a latent electrostatic image formed on a photoconductor with a one-component type developer has a charging device comprising at least two charging members for charging the developer held in a developer container. The first charging member serves both as a doctor blade and for regulating the amount of the developer on the development roller, and the second charging member charges the developer before it is charged by the first charging member. In the second charging member, there is formed a hole for allowing the developer to pass therethrough. The developer scraped by the first charging member is returned to the developer container through the hole and part of the scraped developer is carried back to the first charging member, so that a developer circulation path is formed in the charging device. While passing through the developer circulation path, the developer is charged further, whereby the developer is sufficiently charged before it is actually used for development.
