PURPOSE:To improve toner sticking preventiveness and to prevent the malfunction of a machine by the discharge of static electricity by adding a carbonaceous conductivity applying agent to a compsn. prepd. by using a thermoplastic polyether arom. ketone as a base material and compounding heat resistant reinforcing fibers, inorg. filler, etc. therewith. CONSTITUTION:The titled stripping claw is obtd. by injection molding of the compd. consisting of 95-40pts. (by weight) thermoplastic polyether arom. ketone (PEEK), 5-60pts. heat resistant reinforcing fibers such as potassium titanate fibers, asbestos fibers or arom. polyamide fibers, 0-40pts. filler such as talc and 3-20pts. conductivity applying agent such as ketine black or acetylene black. The stripping claw for fixing consisting of such PEEK as the matrix has the excellent sharpness of a blade edge, heat resistance, impact resistance, non-attack characteristic to a roll surface, moisture resistance, etc. and therefore the durability and shape stability of the blade edge are improved. The electric conductivity is provided thereto and the static electricity is removed therefrom. There is no sticking and solidifying of a toner even if the blade edge is coated with 'Teflon(R)'. In addition, the malfunction of the circuit by the discharge is prevented and this stripping claw is used for a copying machine, printer, printing machine, etc.
