ABSTRACT:
An image-forming apparatus which controls the temperature of the contained thermal fixing device on standby, based on the image formation history information on times of past image formations, etc., to efficiently reduce the power consumption during standby without lowering the availability factor of the image-forming apparatus, which is constructed so that the data on use frequency, including the current time, the number of copies made, etc., (image formation history information) is stored each time an image-forming process is executed, the control section sums the image formation history information on an hourly or other basis, and the temperature of the thermal fixing device on standby is controlled based on the current time-related image formation history information summed on an hourly basis.
