Abstract
In a contact fixing system in which a heat-softened toner image is fixed onto a sheet material by being pressed against the sheet material in a nip between the peripheral surfaces of two circulating fixing members, such as rollers pressing one against the other or a roller pressing against an image carrying belt, residues of the toner of an image and paper dust are removed from the surface of a fixing member in a cleaning zone beyond the fixing nip by moving in rolling contact with that surface a circulating cleaning surface, such as a roller surface, to which the toner adheres preferentially and which has a multiplicity of spaced-apart perforations formed therein and so disposed that with continued movements of the cleaning surface through the cleaning zone a toner layer formed on the cleaning surface is repeatedly pressed thin and excess toner present in it is displaced to the perforations for discharge through them into a cavity inside the cleaning member.
