Abstract
A device for removing residual toner from the surface of a photoreceptor after the transfer of a toner image from the photoreceptor surface to another surface comprises a fur brush for lightly sweeping residual toner particles on the surface of the photoreceptor to align the particles substantially in streaks along the sweeping direction and a magnetic roll for picking up the aligned toner particles by the magnetic attraction force of the magnetic roll. The fur brush is positioned adjacent to, and in a slight contact with, the surface of the photoreceptor. The magnetic roll is disposed adjacent to the surface of the photoreceptor and at the trailing side of the fur brush along the path of relative movement with the photoreceptor.
