  • Blade and seal for preventing migration of toner particles from a developer roll in an electrophotographic printer
    Patent number: 5166733
    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.
