Abstract:
A fixing device includes a housing, a magnetic flux generation source, a first rotary body, a second rotary body, a first core, a second core, a shaft portion, a magnetic shielding body and an air flow generator. The shaft portion has a hollow cylindrical shape, holds the second core on a peripheral surface and includes an internal space extending in an axial direction inside. The shaft portion serves as a rotary shaft in the rotation of the second core. The air flow generator generates an air flow flowing in the internal space of the shaft portion from one end side toward the other end side in the axial direction.
