Abstract:
A power-saving controller comprising:temperature detection means for detecting the temperature of a heating load used in an image-forming apparatus;temperature control means for controlling the driving of said heating load based on an output from said temperature detection means;a power-saving key for instructing transfer to a power-saving mode in which said heating load is controlled to have a power-saving temperature lower than a target temperature of said heating load used when said image-forming apparatus stands by;selecting means for manually selecting the power-saving temperature of said heating load in the power-saving mode; andpower-saving control means for controlling said temperature control means so that said heating load is controlled to have the power-saving temperature selected by said selecting means when an instruction for performing transfer to the power-saving mode is input by said power-saving key,wherein when the power-saving temperature selected by said selecting means is higher than a predetermined temperature, said power-saving control means controls said heating load so that said heating load is controlled to have the predetermined temperature, after a predetermined period elapses in the power-saving mode.
