IMAGE FORMING APPARATUS, POWER CONTROL METHOD THEREFOR, AND STORAGE MEDIUM STORING POWER CONTROL PROGRAM THEREFOR

摘要

An image forming apparatus that is capable of reducing power consumption by controlling electric power without employing a complex control in a unit of a small-scale module. The image forming apparatus executes processes concerning image formation in units of modules. A waiting unit makes a module wait an execution of a process until power supply stabilization time lapses after starting power supply to the module as a power control target. A measurement unit measures lapsed time until the power control target module has processed predetermined unit data after starting power supply. A determination unit determines whether the power supply to the power control target module is turned OFF based on the lapsed time acquired by the measurement unit.
