(57) [Abstract] [Purpose] The present invention provides a separation claw of a copying machine with heat deformation resistance, heat aging resistance, impact resistance, heat fatigue resistance, heat load resistance, low attack to a mating roller and separation claw. The shape of the tip of the blade is excellent in stability and non-adhesiveness to toner. [Structure] Resin heated at a heating rate of 4 ° C./min under a load of 100 kgf / cm 2 having an inner diameter of 1 mm and a length of 10 When extruded from a mm nozzle, the melt viscosity is 48,000. The temperature indicating 0 poise is defined as the flowing temperature, and 9Al 2 O 3 · 2 is added to the liquid crystal polyester having a flowing temperature of 340 ° C or higher. Shaping the separating claw in B 2 O 3 or 2Al 2 O 3 · B liquid crystal polyester resin composition obtained by adding 2 O 3 aluminum borate whisker. In addition, P is applied to the separating nail at 330 ° C or higher. The FA coating improves the non-stick property. |
