摘要:
An image heating apparatus includes a rotatable image heater including: an electroconductive layer; a pressor, press-contacting the heater, for forming a nip in which an image on a recording material is to be heated; an urging member, provided inside the heater, for urging the heater toward the pressor; and an excitation coil for induction-heating the electroconductive layer. When the length of the heater with respect to a rotational axis direction thereof is Lb, the length of the pressor with respect to the rotational axis direction is Lr, the outside distance of bent portions of the coil at both end portions thereof with respect to the rotational axis direction is LcoilA, and the inside distance of the bent portions with respect to the rotational axis direction is LcoilB, the lengths Lb and Lr and the distance LcoilA and LcoilB satisfy the following relationship: LcoilA>Lb>Lr>LcoilB.
