Abstract

A development station for applying toner to an electrostatic image includes a rotatable magnetic core and a roughened sleeve on which developer moves to develop the image. The outside surface of the sleeve contains fine extrusion-formed serrations, which serrations provide a roughness for the outside surface contributing to movement of developer in response to rotation of the magnetic core.
