ABSTRACT:
Method and apparatus for developing an electrostatic latent image formed on the surface of an electrostatic latent image-bearing material by applying a powdery developer, wherein the surface of a developer-retaining member retaining a layer of the powdery developer thereon is brought into rolling contact with the surface of the image-bearing material in such a relation that a reservoir zone of the developer is formed at least upstream of the zone of rolling contact between the two surfaces, and the developer in the reservoir zone is physically disturbed.
