Description of the Related Art A conventional composite apparatus having an electrophotographic printer unit has a toner image transferred onto a sheet, a fixing roller, a heat roller having a heat source such as a halogen lamp and a surface covered with elastic rubber. It is fixed by being nipped and heated in the nip of the pressure roller. According to this method, the electric power supplied to the heat roller of the fixing device becomes very large, so that the power saving state is automatically entered when the compound device is not used for a predetermined time. In this mechanism, a timer is started when the operation of the multifunction device is completed, and when the measured time exceeds a predetermined time, the power saving state is entered. If a new operation is performed after the timer has started and before the power saving mode is entered, the time measured by the timer is cleared, and when this operation ends, the timer starts again. In this power saving state, there is a preheat mode that is set to a temperature lower than the fixing temperature during copying, and in the power saving state there is an auto shut-off mode that cuts off the power supply to the fixing device. Therefore, when the operation is performed, the temperature of the fixing device is controlled so as to be returned to a predetermined copy temperature.

は、電力を供給しない節電状態もあり得る。The printer section 8 includes a sheet feeding / conveying means (not shown), an image forming means (not shown), and a fixing device 9.
The toner image is transferred to the paper fed from the paper feeding cassette by the image forming means, and the toner image is formed by being nipped and heated by the nip between the heat roller and the pressure roller of the fixing means. It is fixed. Specifically, the fixing device 9 has a heat roller made of a base material having a high thermal conductivity such as aluminum and having a heater such as a halogen lamp built therein, and a heat roller around the roller having a good thermal conductivity such as aluminum. A pressure roller which is covered with an elastic layer made of urethane rubber and further has a release layer made of a fluororesin such as PTFE, a temperature detecting means for detecting the surface temperature of the heat roller, a power source for the heater, ON / OFF of the heater
And a fixing temperature control means for controlling them. The temperature control of the fixing device 9 is performed during printing and in a normal stable standby state.
It is changing at the set temperature of 180 ± 5 ° C. In this case, when the surface temperature of the heat roller, which is converted from the value detected by the temperature detecting means, falls below a first fixing threshold value (175 ° C. in this case) determined from the temperature to be controlled, the switching is performed. The temperature of the heat roller is raised by turning on the means, and when the temperature exceeds the second fixing threshold value (185 ° C. in this case) determined from the temperature to be controlled, the switching means is turned off and the temperature of the heat roller is changed to the sheet. Threshold control is performed, in which heat is taken away by the air and the temperature drops. Also, when shifting to the power saving mode, at a temperature lower than the set temperature above and not consuming much power,
In addition, the power saving standby temperature that can immediately rise to the set temperature of 185 ° C. is maintained. When the heat capacity of the fixing unit 9 is small or when priority is given to saving power consumption in the power saving state, there may be a power saving state in which power is not supplied.
