ABSTRACT:
In the development of xerographic images wherein the latent image is in the form of a periodic charge pattern, polar or polarizable toner particles are employed. It is desirable to utilize a development system that will bring the polar or polarizable toner into contact with the periodic charge pattern without triboelectrically charging the particles. To achieve this aim, an apparatus and method are described for moving the polar or polarizable toner particles through a development zone at substantially the same speed and in the same direction as that of the imaging member.
