Abstract
In a cleaning apparatus, a film as a guide plate for guiding cleaned toner into the apparatus is bonded to a holder, which is screwed to a housing. The screwing is loosened by a predetermined amount for providing a gap between the holder and the housing. If the housing and the seal member are thermally expanded by heat from a fuser during the operation of a image formation apparatus and a difference occurs between the expansion amounts of the housing and the holder, the gap absorbs the expansion amount difference and a force of warp, distortion, etc., does not act on the holder. Therefor, deformation of the film held by the holder can be prevented and trouble such as toner not being guided into the apparatus and scatters can be prevented.
