Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a conductive sheet which has a volume resistivity in a (semi)conductive region in a state little varied at places, has good slipperiness, is substantially not curled, and has good mechanical strength, to provide a method for producing the same, and to provide an electric charge-controlling member using the sheet. SOLUTION: This conductive sheet formed from a resin composition comprising 100 pts. wt. of nylon 12 (co)polymer and 15 to 70 pts. wt. of conductive carbon black is characterized by having a sheet thickness of 30 to 800μm, volume resistivity of 1.0×101to 1.0×1012Ωcm, and an arithmetical average roughness Ra of 0.06 to 1.0μm for each of both the surfaces.
