ABSTRACT:
In the development of nonuniform latent images on an imaging member, wherein xerographic 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 latent image without triboelectrically charging the particles and permitting use of nonmagnetic particles when the image is electrostatic and without demagnetizing the latent image when it is magnetic. To achieve this aim, a dielectric brush having convergent electrostatic fields is disclosed and claimed.
