ABSTRACT:
A cleaning device of a charging unit in an image forming apparatus using an electrophotographic process for cleaning a corona wire. The cleaning device comprises an elongated shield case having a guide slit in a central portion extending in a lengthwise direction of a photosensitive drum; a cleaning shaft guide containing a bore therein, mounted to the guide slit and adapted to slide along the guide slit, a cleaning shaft having a handle and an integrally connected body inserted into the bore and adapted to maintain a cleaning member at a distance from the corona wire during non-cleaning of the corona wire, and to allow, upon application of force, the cleaning member to resiliently press against the corona wire and move along the corona wire while being held in frictional contact with the corona wire during cleaning of the corona wire by way of an elastic spring disposed between the handle of the cleaning shaft and the cleaning shaft guide.
