Abstract

Fuser apparatus for fixing toner images 42 to substrates 40 comprising a heated fuser roll 16 structure and a backup roll structure 18 forming a nip through which the substrates pass, with the toner images contacting the heated fuser roll struc~- ture to thereby soften the toner images. The heated fuser roll structure is characterized by the provision of an outer layer 22 of Teflon material to which a liquid release agent such as silicone oil is applied. A cleaning roll structure 50 for removing toner offset to the fuser roll structure is provided and comprises an outer surface 54 having a high affinity for toner offset to the fuser roll structure. The cleaning roll structure comprises a shaft 52 which is stationarily supported relative to the fuser roll structure

ROLL FUSER (Cont~d)

and in such a position as to support one or more cleaning roll sleeves in contact with the fuser roll structure.
The sleeve is freely supported by the shaft such that
there is relative slippage between the cleaning roll

sleeve and the fuser roll structure when the accumulation
of toner on the cleaning roll is at a minimum. However,
as the toner builds upon the cleaning roll sleeve and the
friction between the roll and the fuser roll structure

increases the sleeve is automatically moved by...
