ABSTRACT:
An electrophotographic copying machine includes a main housing and an internal frame which can be detachably mounted in position defined in the main housing. The internal frame supports a photosensitive member in the form of an endless belt and a grid electrode. The main housing is provided with a corona discharger comprised of a corona wire and a casing partly surrounding the corona wire to define an opening through which corona ions are emitted. When the internal frame is mounted in position in the main housing, the grid electrode comes to be located opposite to the opening thereby functioning as a part of the corona discharger. Thus, when the internal frame is dismounted, the opening of corona discharger is exposed thereby allowing easy access to the corona wire.
