ABSTRACT:
The present invention relates to a paper releasing guide-claw for a copying machine and a method for producing the same including molding a material containing from about 50-90% by weight of a polyimide consisting essentially of recurring units of the formula: ##STR1## from about 5 to about 40% by weight of a fibrous reinforcing material, and from about 5 to about 30% by weight of a solid lubricant, wherein the sum of the content of the fibrous reinforcing material and the solid lubricant is from about 10 to about 50% by weight, heat treating the molded guide-claw at a temperature of from about 250.degree. C. to about 340.degree. C. for a time sufficient to increase the density of the polyimide component by 1.5%.
