Abstract
A fuser includes a magnetic flux generation unit to generate a magnetic flux, a heating member which is heated by electromagnetic induction of the magnetic flux, a fuser member to contact the heating member and heat a toner image so as to fuse the toner image onto a recording medium, a detection unit to directly or indirectly detect a contacting state of the fuser member at an edge in a width direction of the fuser member with the heating member, and a magnetic flux adjusting member to reduce the magnetic flux acting upon an end in the width direction of the heating member in accordance with a detection result of the detection unit.
