ABSTRACT:
A fixation apparatus having a good fixability in its longitudinal direction and an image forming apparatus are provided. The fixation apparatus includes an electromagnetic induction heating member which is a hollow rotation member, and a magnetic flux generation member for causing the electromagnetic induction heating member to generate heat by generating magnetic flux in the electromagnetic induction heating member. The fixation apparatus fixes a toner image on a recording material by imparting heat energy by heat generation of the electromagnetic induction heating member to the recording material to be conveyed. The electromagnetic induction heating member has a different thickness in the longitudinal direction thereof and a uniform diameter at a surface facing the magnetic flux generation means in the longitudinal direction.
