Abstract
A fixing unit for fixing a toner image onto a sheet passing between a first element and a second element pressed against the first element includes a looped coil surface formed with a coil so that the coil surface generates a magnetic field for induction-heating the first element, the coil surface including an inner edge defining an opening region; an upright wall disposed inside the opening region, an opening being formed in the upright wall; a center core disposed along the opening region, the center core including a conductive shaft and a magnetic tube configured to at least partially cover the conductive shaft; and a nonconductive cap inserted into the opening, the nonconductive cap partially covering the conductive shaft to electrically insulate the coil from the conductive shaft.
