ABSTRACT:
A cleaning member is elastically forced on a bearing surface, for cleaning off particles from the bearing surface by a movement of the bearing surface relative to the cleaning member. In particular, the cleaning member has first and second portions capable of forming first and second ramps having first and second acute internal angles on upstream and downstream sides of a contact region with respect to a moving direction of the bearing surface, respectively, the contact region being defined between the cleaning member and the bearing surface when the cleaning member is forced on the bearing surface.
