Abstract
A fixing device for fixing a toner image on a recording material includes an endless belt, a rotatable member to form a nip, first and second stretching rollers in contact with an inner peripheral surface of the belt, and first and second heaters to heat the first and second stretching rollers, respectively. An amount of heat generation of the first heater is larger than an amount of heat generation of the second heater. At a start up of the fixing device, heating of the first heater is started by a first electric power prior to heating of the second heater, and the heating of the second heater is started by a second electric power smaller than the first electric power after a temperature of the first stretching member reaches a target temperature.
