Patent ID: 8554097

Claim:
An image heating apparatus, comprising: image heating means for heating an image on a recording material with the heat; a belt member configured to form a nip which nips and feeds the recording material by pressing said image heating means; a belt position adjusting means for adjusting a position of said belt member in a widthwise direction; a first temperature detecting member which is provided in a minimum sheet processing region for the recording material of a minimum size, and detects a temperature of said image heating means; a first controller configured to control electric power supply to said image heating means on the basis of an output of said first temperature detecting member; a second temperature detecting member, provided at an end of said image heating means, configured to detect a temperature of said image heating means, wherein said second temperature detecting member is capable of detecting a temperature of an area of said image heating means which is out of contact with said belt member when said belt member is in one position with respect to the widthwise direction, and is capable of detecting a temperature of an area of said image heating means which is contacting said belt member when said belt member is in another position with respect to the widthwise direction; and a second controller configured to control the image heating operation at the time of the continuous image formation on the basis of the temperature of the area of said image heating means which is out of contact with said belt member and to control the start of the image heating operation on the basis of the temperature of the area of said image heating means which is in contact with said belt member.
