Abstract
An induction heated roll apparatus includes a roller main body, an induction heating mechanism, and a cooling mechanism. The induction heating mechanism heats the roller main body, while the cooling mechanism cools the roller main body and/or the induction heating mechanism using a cavity portion between the roller main body and the induction heating mechanism. The cooling mechanism has intake apertures and discharge apertures that are formed in a journal flange portion and communicate with the cavity portion, a suction mechanism that suctions a gas in the cavity portion through the discharge apertures, and a mist supply mechanism that supplies mist to the intake apertures.
