Abstract
A development apparatus for developing images with magnetic toner particles contained in magnetic developer material. The development apparatus has a magnetic development roller and a device for removing a partial amount of magnetic chains of the developer material from the magnetic development roller. The device includes a first magnet generating a first magnetic field for standing the magnetic chains on a first end, and a second magnetic generating an opposite magnetic field for standing such chains on a second and opposite end. The device also includes a skiving plate that is positioned between the first and second magnetic fields.
