磁気ブラシ現像装置。 A developing image is supplied in a developer supplying section onto a developing roller consisting of a rotatably provided cylindrical sleeve and a magnetic roller provided inside the sleeve and consisting of a main pole, a transport pole, and a repulsion pole. A magnetic brush of the agent is formed, and the electrostatic latent image on a latent image carrier provided opposite to the developing roller is rubbed with the magnetic brush to perform development. The magnetic brush developing device is configured such that the repellent pole is separated by a developer stripping section of a developing roller in which the repelling pole is disposed and collected in the device housing. What is claimed is: 1. A magnetic brush developing device comprising a rotating means for displacing the developer from the developing roller to the developer supplying section and stopping the supply of developer to the developing roller during non-development.
