ABSTRACT:
An electro-photographic image forming device that is capable of controlling a print speed and a method for controlling the same, wherein the electro-photographic image forming device has an engine mechanism including a laser scanning unit, a developing unit, a transfer roller, and a fixing unit. The electro-photographic image forming device further includes a first driving unit for driving the laser scanning unit, a second driving unit for driving the photosensitive medium, the developing unit, the transfer roller, and the fixing unit, and a controller for controlling the first and second driving units so as to have the laser scanning unit driven at a first driving speed and to have the photosensitive medium, the developing unit, the transfer roller, and the fixing unit, driven at a second driving speed in the engine mechanism when it is determined that a print mode for printing desired print data is set to a draft mode.
