PROBLEM TO BE SOLVED: To provide a heating system for improving electric power-saving and productivity while reducing the space and cost of a device by constituting a compact magnetic flux shielding mechanism by reducing the waiting space made of magnetic shield members and a space of a driving means in the heating system using a magnetic flux shield means as a paper nonfeeding part temperature rise countermeasure in an electromagnetic induction heating method. SOLUTION: A heating part N has a magnetic flux adjusting means for changing the density distribution in the heating part length direction for crossing the carrying direction of a heating object material of a magnetic flux generated by a magnetic flux generating means 5. The magnetic flux adjusting means has the magnetic flux shield members 3a and 3b, and moving means 4, 11, and 20 for moving these magnetic flux shield members to a position for adjusting the magnetic flux generated by the magnetic flux generating means. The position for adjusting the magnetic flux generated by the magnetic flux generating means is a position for checking the magnetic flux in a magnetic circuit for passing the magnetic flux shield members through an inside space of an exciting coil 5 of the magnetic flux generating means.
