The combination of a pressure fixing roller for an electrophotocopying machine and a scraping device operatively associated with the roller for removing toner material accumulated on the roller. The scraping device includes an angled blade having a scraping portion and a supporting portion oriented at an acute angle with respect to the scraping portion, and a plastic bracket surrounding the supporting portion of the angled blade and having a first, angled, reinforcing member extending along most of the downstream side of the scraping portion of the angled blade relative to the rotation of the roller and a second, smaller, angled, stiffening member extending along a small portion of the upstream surface of the scraping portion of the angled blade and terminating in a direction substantially parallel to the scraping portion of the angled blade.
