ABSTRACT:
A chemical adsorption film possessing a fluorocarbon group through siloxane coupling is applied on the surface of a photoimaging component such as a photoconductor, the surface of a cleaning blade, the surface of a fixing roller, the surface of a separation pawl used in offset of paper, the surface of a corona wire, or the surface of a corona grid. Further according to the invention, the chemical adsorption film is laminated via a siloxanebased inner layer, the inner layer being bonded by covalent bonds to the surface of the device, the inner layer and the chemical adsorption film being bonded together by covalent bonds. Furthermore according to the invention, since the chemical adsorption film of the invention is an ultrathin film, on the order of nanometers or Angstroms, it does not spoil the properties of the separation pawl such as mechanical strength.
