PROBLEM TO BE SOLVED: To obtain a coated paper exhibiting printability especially severely required to the coated paper in recent years while the coated paper is made at high speed having≥1,300 m/min papermaking speed. SOLUTION: The method for producing the coated paper is characterized in that the following continuous steps are incorporated in this order in on-machine: (1) a step for carrying out papermaking by gap type twin wire former for jetting a paper material from a head box into a space between two wires forming loops and forming a paper layer; (2) a step for forming wet paper by a dehydration means using a suction (forming) roll and/or blade in a wire part; (3) a step for drying the wet paper; (4) a step for carrying out blade coating of the paper with an aqueous coating solution mainly containing an adhesive and a pigment by a jet fountain system using an applicator 90 and a blade 91; and (5) a step for carrying out planarizing treatment of the resultant paper by a heated calender 70 composed of a combination of a metal roll and an elastic roll having at least 2 nips and constituted in a plural stages.
