A cleaning member for cleaning e.g. the fixing surface of a thermal contact fixing device

摘要

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, a few millimetres thick, of a high-viscosity polymeric material sticky at room temperature. The polymeric material is a polymer or polymeric mixture having a viscosity between 10<4> and 10<6> Pa.s at 20 DEG C. A very suitable polymer, for example, is polyisobutylene, which has 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 deposited on the surface thereof.
