A method for producing a toothed belt (10) having a belt section (13) and a tooth section (14) projecting from the belt section (13), which comprises a first step of applying an aqueous treating agent containing a latex of a first rubber and a first vulcanizing agent on a fiber sheet, followed by drying, to thereby form a reinforcing sheet (12) having a fiber sheet and a coating film formed on the fiber sheet, and a second step of vulcanizing the first rubber and a second rubber at the same time in the state in which the reinforcing sheet (12) and a rubber composition being the material of the tooth section (14) and containing the second rubber and a second vulcanizing agent are closely contacted with each other, to thereby reinforce the surface of the tooth section (14) with the reinforcing sheet (12). The above aqueous treating agent comprises the vulcanizing agent in the range of 10 to 100 parts by mass relative to 100 parts by mass of the first rubber.
