Abstract

A magnetic brush developer roll in which the magnet utilized therein generates a sinusoidal field. The developer roll deposits magnetic toner particles on a latent image recorded on a photoconductive member. The sinusoidal field applies a magnetic force on the toner particles which may be made spatially constant preventing density fluxuations in the developed image. Lateral forces, which may reduce image quality by sidewise spreading of the toner during the transfer of the toner from the photoconductive surface to the copy sheet,
