Zusammenfassung:	The present invention provides an extruded external drum for an imaging system. The external drum is extruded from a light-weight and strong material such as an aluminum alloy. The external drum includes a thin outer wall (40), a hollow cylindrical hub (42), and a plurality of thin radial spokes (44) extending between the cylindrical hub and the outer wall. The present invention provides a stiff external drum having low rotational inertia.
