Abstract
Contact fusing system for utilization in the process of forming toner images on support sheets. The system is characterized by the provision of structure for cleaning toner material from an elastomeric backup member cooperating with a heated fuser member to move support sheets bearing the toner images therebetween with the toner images contacting the heated member. The cleaning structure comprises a sleeve of tetrafluoroethylene which is heat shrunk onto an angular-shaped support member whereby approximately one-third of the sleeve forms a cleaning surface which is contacted intermediate the ends thereof by the elastomeric backup member.
