A copier having a scanner section and a fixing device. The scanner section has an exposure lamp (10), and the fixing device has an upper roller (60) and a lower roller (61). The upper roller (60) incorporates a main heater lamp (62) and a sub-heater lamp (63). While the scanner section is operating, that is, while the exposure lamp (10) remains on, the sub-heater lamp (63) is off, and only the main heater lamp (62) is on. When the exposure lamp (10) is turned off, the main heater lamp (62) and the sub-heater lamp (63) are turned on, thus maintaining the surface temperature of the upper roller (60) within a predetermined range. The exposure lamp (10) and the sub-heater lamp (63) consume the same current. Hence, the total current consumed in the copier always remains less than (15A). <IMAGE> |
