ABSTRACT:
In an electrophotographic printer having a photoreceptor surface for the creation of electrostatic latent images thereon and a rotating roll for conveying toner particles to a development zone adjacent the photoreceptor surface, an apparatus prevents the migration of toner particles from the roll. A blade, in contact with the roll adjacent one end thereof, causes toner particles adhering to an area of the roll to be moved toward the roll center as the roll rotates.
