Zusammenfassung:A transfer assist blade (186) for an electro-photograhic printing machine provides the necessary stiffness to allow complete transfer of a toner image while avoiding excessive bending stress in the blade, such a blade (186) is made up of a semiconductive polyester layer (188) bonded to a non-semiconductive polyester layer (189). A third (190) and fourth (191) layer of high molecular weight polyethylene are bonded to the second layer (189). These third and fourth layers (190,191) do not extend the full length of the blade (186) to provide supplemental stiffness while avoiding excess bending stress.
