Abstract
A magnetic support member, and apparatuses including the support member for magnetic cleaning or magnetic development in an electrostatographic reproducing machine. The magnetic support member is formed of a composite composed of elongated bodies of a magnetic material having a high magnetic permeability in a non-magnetic matrix. The magnetic support member includes a support surface and the elongated bodies are aligned with respect thereto such that the direction of their long dimension is generally perpendicular within about .+-. 30.degree. to the support surface or to a tangent to the support surface.
