PURPOSE:To enhance abrasion resistance, friction resistance, oil absorptivity, resistance to chemicals, cleanability, uniform coatability, heat resistance, and dimensional stability by forming a fibrous structure having aramide type resin films scattered on the surface and a gas permeability of 3-25cc/cm<3>/sec through the surface. CONSTITUTION:The surface of the fibrous structure has scattered aramide type resin films and a gas permeability of 3-25cc/cm<3>/sec through the surface, and when <3cc/cm<3>/sec, a function of removing a remaining toner becomes deficient, and when >25cc/cm<3>/sec, it is made difficult to diffuse a smoothing agent to be applied to said structure after treatment. The aramide type resin film is formed on the surface of the structure formed into a flat or cylindrical shape by impregnating or coating the structure with the dope of this resin and solidifying the dope by a wet or dry process. |
