摘要： A power control apparatus includes a power detection circuit to detect DC power converted from AC power supplied from a power supply and to be supplied to a control board of an image forming apparatus. The power control apparatus includes circuitry configured to, in response to a first printing operation performed by the image forming apparatus, calculate fluctuations in the DC power in each preset control period from a start of the first printing operation until stabilization of the DC power. The power control apparatus includes, in response to a printing operation subsequent to the first printing operation performed by the image forming apparatus, determine allocation of the AC power to a fixing device of the image forming apparatus in a next preset control period based on power obtained by adding, to the DC power, an average of the fluctuations in a plurality of preset control periods.
