Abstract
A cleaner for a toner fixing device in an electrophotographic machine or the like. A housing is provided near a pair of fixing rollers, and an endless-belt type felt member is partially disposed in the housing in a folded state. The remaining portion of the felt extends outside of the housing and contacts one of the fixing rollers while the felt is being pressed upon by a drive roller and pressure member. The felt is moved at a slow speed, preferably such that its service life corresponds to one rotation of the felt.
