Abstract
An image heating device includes: a rotatable heater for heating an image on a recording material; a pressor for pressing the heater to form a nip in which the recording material is to be nip-conveyed; a belt for heating and contacting the heater; a first member for heating the belt while pressing the belt against the heater; a second member, provided downstream of the first member with respect to a rotational direction of the heater, for heating the belt while pressing the belt against the heater; a first portion for heating the first member by energization; and a second portion for heating the second member by energization. Each of the first and second portions is supplied with power so that a maximum of the power supplied to the first means is smaller than that of the power supplied to the second portion.
