ABSTRACT:
A power saving method of an image forming apparatus using an electrophotographic developing unit includes the steps of: beginning a counting operation upon occurrence of an error state in the image forming apparatus, when the image forming apparatus is in a print stand-by mode; determining whether a current counting value reaches a reference comparison value for executing a power saving mode; determining whether the error state is removed from the image forming apparatus, when the current counting value has not reached the reference comparison value; increasing the currently counting value by a given counting unit and returning to determine whether the current counting value reaches the reference comparison value, when the error state has not been removed from the image forming apparatus; and executing the power saving mode of driving the image forming apparatus with electric power lower than electric power required for maintaining said image forming apparatus in the print stand-by mode, when the present counting value reaches the reference comparison value.
