Claim 13:
14. An imaging apparatus comprising:
a toner container to accommodate a toner that includes toner base particles and inorganic fine particles containing a peeling auxiliary agent;
a transfer device to transfer the toner to form a toner image on a recording medium; and
an image heating device to heat the toner image formed on the recording medium, wherein the image heating device includes:
an endless belt having an outer peripheral surface to contact the toner image on the recording medium, the endless belt comprising a contact width between a pressing member and a driving roller of the image heating device;
three electrode portions including a first electrode portion, a second electrode portion, and a third electrode portion that are in contact with the endless belt, and spaced apart in a movement direction to form a first heat generation region between the first electrode portion and the second electrode portion, and to form a second heat generation region between the second electrode portion and the third electrode portion; and
a peeling roller around which the endless belt is wound to form a curvature variation in the endless belt, so as to cause the recording medium to peel-off from the endless belt during a heat removal operation,

wherein a portion of the peeling auxiliary agent included in the toner of the toner image is caused to remain on the outer peripheral surface of the endless belt; and
wherein the second heat generation region is located outside the contact width.
