Abstract:
1. An image forming apparatus comprising: an image forming unit adapted to form a toner image on a sheet; a fixing unit adapted to thermally fix, on the sheet, the toner image formed on the sheet by said image forming unit; a temperature detection unit adapted to detect temperature of said fixing unit; an electric power supplying unit adapted to supply electric power to said fixing unit; a setting unit adapted to set a first value to a memory when the temperature detected by said temperature detection unit reaches a target temperature, in a case where said electric power supplying unit supplies a first electric power to said fixing unit; and a mode selection unit adapted to select a first mode in which said electric power supplying unit supplies the first electric power to said fixing unit, in a case where the first value is set to the memory when the image forming apparatus is powered on, and select a second mode in which said electric power supplying unit supplies a second electric power less than the first electric power to said fixing unit, in a case where a second value different from the first value is set to the memory when the image forming apparatus is powered on, wherein said electric power supplying unit controls the electric power supplied to said fixing unit according to whether the first mode or the second mode is selected by said mode selection unit, and wherein said setting unit changes the first value of the memory to the second value, in a case where the first value is set to the memory when the image forming apparatus is powered on.
