Image heating device with temperature sensors provided in sheet passing portion and non-sheet passing portion

摘要

An image heating device (10) includes : a heating member (1) having a heater (2) that is in contact with a bearing member (P), which bears an image, and heats the image, a first temperature detecting member (5a) that is disposed above a surface of the heating member with a gap therebetween and detects a temperature of the heating member, a second temperature detecting member (5b) that is disposed in contact with the surface of the heating member and detects a temperature of the heating member and a controller (100) for controlling a supply of a power to the heater on the basis of a detected output of the first and second temperature detecting members, wherein the controller controls the supply of the power to the heater on the basis of the detected output of the first temperature detecting member at the time of heating the image and controls the supply of the power to the heater on the basis of the detected output of the second temperature detecting member at a time of standby.
