Abstract
A cleaning member for cleaning a surface which, for example in an image recording device, is brought into contact with toner powder or an image receiving material carrying toner powder. The cleaning member comprises a surface layer of a high-viscosity polymeric material that is sticky at room temperature. Preferably, the polymeric material is a polymer or polymeric mixture having a viscosity between 10.sup.4 and 10.sup.6 Pa.s at 20.degree. C., and a very suitable polymer is polyisobutylene, having a molecular mass of about 100,000. The cleaning member is preferably provided with mixing means for mixing into the mass of the sticky layer impurities that are deposited on the surface thereof.
