According to this invention, a rolled sheet rolled by a reduction roll of a rolling mill is divided into a plurality of areas in a direction of its width, and sheet flatness or thickness values are measured in the plurality of areas. Bending forces, leveling value, shift amounts, and the like applied, by actuators respectively arranged at drive and work sides of the reduction roll, from the drive and work sides of the reduction roll are calculated in accordance with the sheet flatness or thickness measurement values and influence coefficients of the actuators. The actuators on the drive and work sides of the reduction roll are independently operated in accordance with these operation amounts.
