PURPOSE: To obtain a semiconductive fluororesin composition useful as an electrophotographic material, etc., capable of showing a high volume specific resistance, by blending a thermoplastic fluororesin with a polymer type antistatic agent such as a polyalkylene glycol monoacrylate-based copolymer and an ionic electrolyte. CONSTITUTION: A mixture of 97-40 wt.% of a thermoplastic fluororesin, 20-70 wt.% of a polyalkylene glycol mono(meth)acrylate of formula I (R1 is H or CH3 ; R2 is a 2-4C alkylene chain; R3 is H or an alkyl; (n) is an integer of 3-100) and 3-60wt.% of a polymer type antistatic agent of formula II (R4 is H or CH3 ; R5 is a 1-3C alkyl) is blended with 0.05-5 pts. wt. of an ionic electrolyte (e.g. lithium thiocyanate) based on 100 pts.wt. of the mixture to give the objective semiconductive fluororesin composition having excellent processability, capable of showing 1×10<7> to 1×10<11>Ω.cm volume specific resistance with slight environment dependence, change with time and bleedout.
