A toothed belt includes a tensile body embedded therewithin and the tooth surface thereof coated with a tooth sheet, wherein the tooth sheet is treated by RFL solution including inorganic pigments. The toothed belt, after treatment by RFL solution, forms an RFL solution impregnated layer at the tooth surface thereof. Resorcin and formaldehyde are compounded in the mole ratio of 1:1 to 1:3, while resorcin and formaldehyde are compounded with latex in the weight ratio of 1:5 to 1:15. solid content of RFL solution is compounded with inorganic pigments in the weight ratio of 20:1 to 1:2. The inorganic pigment is selected from those other than black colored series.
