A fixing device includes: a magnetic field generating component that
generates a magnetic field; a fixing member including a heat generating
layer that is electromagnetically induced by the magnetic field to
generate heat; a support disposed at an inner side of the fixing member;
a pressure rotating body that applies pressure to the fixing member in
the direction of the support; and a pair of magnetic circuit forming
members that are disposed with the fixing member and the magnetic field
generating component being placed therebetween and can be used while
having either elastic deformation or plastic deformation applied thereto.
