ABSTRACT:
An electrophotographic image forming device includes a toner container installed inside a photoconductive drum to provide toner to a developing unit. Toner that is removed and collected by a cleaning unit can be reused, thus reducing toner cost. Also, since the toner container is installed inside the photoconductive drum, the image forming device can be made compact, and an installation space is not restricted when the developing unit is installed within the image forming device. Further, since the used toner is re-used, the interior portions of the image forming device are not contaminated.
