Abstract
A method and apparatus involving the stopping and starting of the development of images, using hybrid development, to insure proper charging of the donor toner layer. A second (e.g. magnetic brush) roll is used to place toner on the donor roll or remove toner from the donor roll depending upon whether the development of images is stopped or started.
