Abstract
The present invention relates to a cleaning device for a fixing unit used, for example in an electric photocopier, for fixing a developed image on a support. The fixing unit is formed by a fuser assembly, in contact with which there moves a film that is rolled up to form an endless belt. The film is set in motion by a drive roller which transmits a drive torque to the belt. The cleaning device removes contaminating particles from the external surface of the drive roller in order to keep constant the coefficient of friction as between the film and the drive roller.
