摘要： Stripping fingers for use in a copying machine, molded of a liquid crystal polyester resin composition containing a liquid crystal polyester having a flow temperature of 340.degree. C. or higher and aluminum borate whiskers. The stripping fingers have excellent heat deflection resistance, heat aging resistance, thermal shock resistance, heat load resistance, low attack on the counter roller, good shape retainability of the finger edges, and good non-stick property against toner. Coating with PFA at 330.degree. C. or higher on the stripping finger increases non-tackiness.

摘要： The aromatic polysulfone resin composition of the present invention can be produced by mixing 100 parts by weight of an aromatic polysulfone resin and 0.1 to 5 parts by weight of a hydrotalcites and/or a zeolite. Molded articles formed of said composition have a mechanical strength and heat resistance inherent to its constituent resin, and generate low-boiling gases and corrosive gases very little. Therefore, the composition of the present invention is best suited for relay parts.
