ABSTRACT:
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.
