1. An image forming apparatus comprising:
a fixing portion configured to fix an image, formed on a recording material, on the recording material, wherein said fixing portion includes a heater configured to generate heat by electric power supplied from a commercial power source; a power source portion configured to supply the electric power to a load except the heater, wherein said power source and the heater are connected with the commercial power source in parallel; a suppliable electric power calculating portion configured to calculate suppliable electric power suppliable to the heater; and a temperature setting portion configured to set, depending on the suppliable electric power calculated by said calculating portion, a control target temperature of said fixing portion in an operation in a stand-by mode in which said image forming apparatus awaits a print instruction, wherein said temperature setting portion sets the control target temperature at a lower value with a larger value of the suppliable electric power. |
