Patent ID: 8655213

Claim:
An image heating device comprising: a rotatable image heating member configured to heat an image on a recording material; a pressing member configured to press said image heating member to form a nip in which the recording material is to be nip conveyed; a belt member configured to heat said image heating member in contact with said image heating member; a first belt heating member configured to heat said belt member while pressing said belt against said image heating member; a second belt heating member, provided downstream of said first belt heating member with respect to a rotational direction of said image heating member, configured to heat said belt member while pressing said belt member against said image heating member; first heating means for heating said first belt heating member by energization; second heating means for heating said second belt heating member by energization, wherein each of said first heating means and said second heating means is supplied with power so that a maximum of the power supplied to said first heating means is smaller than that of the power supplied to said second heating means; a first temperature detecting member configured to detect a temperature of said belt member in an area in which said first belt heating member contacts said belt member; a second temperature detecting member configured to detect the temperature of said belt member in an area in which said second belt heating member contacts said belt member; control means for controlling the energization to said first heating means so that a detected temperature by said first temperature detecting member is a first target temperature and for controlling the energization to said second heating means so that a detected temperature by said second temperature detecting member is a second target temperature; third heating means, provided in said image heating member, for heating said image heating member; and a third temperature detecting member configured to detect a temperature of said image heating member, wherein said control means controls energization to said third heating means so that a detected temperature by said third temperature detecting member is a third target temperature, and wherein the first target temperature and the second target temperature are higher than the third target temperature and are the same temperature.
