Abstract
A waveform pattern of an electric current running through a first heat generating group and a waveform pattern of an electric current of a second heat generating group, controlled by a control unit, in an image forming apparatus of the present invention are different from each other at at least one phase angle in one control period. The percentage of coincidence of a period of phase control of the first heat generating group and a period of phase control of the second heat generating group in the one control period is lower than or equal to 50%.
