ABSTRACT:
In an image forming apparatus, an aperture electrode member, a toner supply device, a fixing device, a main power source and a main base plate are mounted to a main body case while a back electrode roller is disposed on a lid member. When the lid member is closed, the aperture electrode member and the back electrode roller are kept at a 1 mm gap interval. On the other hand, when the lid member is opened, the aperture electrode member and the back electrode roller are completely separated from each other, so that the aperture electrode member can be easily cleaned.
