Abstract

PURPOSE:To reduce an attack time, by providing a plurality of coils wound along the shaft center of this roller independently in a roller made of magnetic substance borne to a fixed shaft freely rotatably, and a plurality of temperature detectors. CONSTITUTION:On a laminated iron core 2 formed along a fixed shaft 1, a plurality of individually wound coil groups 3, and a plurality of temperature sensors 51-56 located near the inner surface of a roller 4 supported around the said fixed shaft freely rotatably made of magnetic substance, are provied. In the constitution above, the temperature of T1 part of the roller is detected at the temperature sensor 51, and when the set temperature exceeds Ts, the control circuit is turned off with a detected output of the sensor 51. The temperature of each part of the roller 4 shows time dependency, the temperatre of each part of roller is uniformly controlled and the rising time can be reduced.
