ABSTRACT:
Method and Apparatus for controlling the sleep-mode of an image forming apparatus includes a movable and heatable element, a drive member for driving the element and a heating member for heating the element while it is being driven by said drive member. The drive member and heating member are controlled to keep the heatable element at a temperature below its normal operating temperature in order to reduce power consumption in the sleep-mode. The drive member and said heating member are energized and de-energized cyclically and the heating member, when switched on, is energized with full power. The movable and heatable element preferably is an intermediate belt for heat transferring/fixing a developed image to a recording medium.
