Abstract
An image forming apparatus includes a first power calculator for calculating a power consumption amount of a driving load unit and a post-processing device based on at least one of measured values of a voltage and a current, which are supplied to the driving load unit and the post-processing device; second and third power calculators for calculating power consumption amounts of a fixing heater driving unit and a controller based on an operating state and an operating time of the image forming apparatus; and a power summing-up unit for calculating a power consumption amount of the image forming apparatus by summing up the power consumption amount calculated by the first power calculator and the power consumption amount predicted by each of the second and third power calculators.
