A device for removing residual toner and other particulate materials deposited on the peripheral surface of a roller in a toner image fixing unit includes a thin perforated member in pressure engagement with the peripheral surface. The perforations are large enough to permit the passage therethrough of the particulate materials, are arranged so that their longitudinal extensions along the direction of advance of the peripheral surface are at least transversely continuous and the perforation edges opposed to the peripheral surface direction of advance are at an angle to such direction. The perforations may be of different shapes, circular, elliptical, triangular, etc. and a receiving receptacle is positioned below the cleaning device.
