ABSTRACT:
An electrophotographic image forming system wherein a visible image is generated on a recording medium in response to a print start command, and the visible image is fixed on the recording medium by heat generated by a heater. The temperature of the heater is controlled by a controller such that the detected temperature of the heater is held at an image fixing temperature when the system is in a printing operation, at a high stand-by level lower than the image fixing level when the system is in a first stand-by state without the print start command being received within a predetermined time period even after a last printing operation, and at a low stand-by level lower than the high stand-by level when the system is in a second stand-by state without the print start command being received even after the predetermined time has passed.
