ABSTRACT:
An apparatus in which a latent image recorded on a belt extending in a direction transverse to a horizontal plane is developed with a developer material. At least two developer rollers are mounted, at least partially, in the chamber of a housing storing a supply of developer material. The developer rollers are spaced from one another and have different diameters. The spacing between each of the developer rollers and the diameters of each of the developer rollers is selected so that a plane tangential to the lowermost region of each of the developer rollers is substantially parallel to the horizontal plane.
