    摘要: A two-cycle electrophotographic copying apparatus includes a rotatable charge retaining member, a charging device, an exposure mechanism, a developing device and a transferring device sequentially arranged around the charge retaining member in the direction of its rotation. During a first rotation of the charge retaining member, a toner image of an original is formed, and during the second rotation of the charge retaining member, the remaining toner is cleaned from the charge retaining member to prepare it for its next succeeding copying operation. The developing device comprises a first sleeve-like member for developing an electrostatic latent image on the surface of the charge retaining member during the first revolution thereof, and a second sleeve-like member for cleaning remaining toner from the surface of the charge retaining member during the second rotation of the charge retaining member and for suppying the removed developer to the first sleeve-like member during the first rotation of the charge retaining member. The second sleeve-like member is movable between first and second positions which correspond respectively to the first and second rotations of the charge retaining member.

    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.
