Abstract
A waste toner collecting apparatus of an electrophotographic image forming device includes a photoreceptive drum having a first slit formed on an outer circumferential surface thereof in a lengthwise direction, through which waste toner removed from the outer circumferential surface of the photoreceptive drum by a cleaning blade contacting the outer circumferential surface thereof passes to be contained therein, and a slit opening/shutting unit which selectively opens and shuts the first silt. Thus, the image forming device can be made compact, and generation of dust can be prevented.
