摘要： An image forming apparatus that enables to continue an operation so that electric power consumption does not exceed a power supply capacity even if an electric current sensor breaks down. A temperature detection unit detects a temperature of a fixing unit that fixes a developed image transferred to sheet material. A failure detection unit detects whether an electric current detection unit that detects an electric current from a commercial power source breaks down. A control unit determines a fixing electric power supplied to the fixing unit based on the temperature detected by the temperature detection unit; and changes the determined fixing electric power so that the electric power consumption does not exceed a limit value and so as not to exceed a predetermined electric power without using an output of the electric current detection unit when the failure detection unit detects a failure of the electric current detection unit.
