Reinigungsvorrichtung für eine Fixiereinheit

摘要

The present invention relates to a cleaning device (13) for a fixing unit (10) which is capable of fixing the image produced for example by an electric photocopier on a support. The fixing unit is formed by a fuser assembly (20), in contact with which there moves a film (14) that is rolled up in a ring configuration to form an endless belt. This is set in motion by an entrainment roller (15) which transmits a drive torque to the belt. The cleaning device (13) removes contaminating particles from the external surface of the entrainment roller (15) in order to keep constant in respect of time the coefficient of friction as between the belt and the entrainment roller.
