Abstract
A new and improved structure for transporting single component magnetic developer for developing latent electrostatic images or for removing residual developer from a charge-retentive surface. In one embodiment of the invention narrow metal strips are embedded in the outer shell or cylinder of a conventional magnetic roll structure. The strips are very pointed adjacent the outer periphery of the shell. The sharp tips ensure a high magnetic field gradient when the magnetic roll disposed internally of the shell is rotated. The thinness of the strips causes them to respond to only the radial component of the magnetic field. Each strip responds to the oscillating radial field component slightly out of phase with its adjacent strip thereby creating a wave gradient along the surface which pulls and tumbles developer over the surface.
