ABSTRACT:
A developing apparatus is constituted of a toner frame for containing developer and a developing frame for holding developer carrier, and both frames include plural pairs of connecting faces, one of which is made separable from the other faces, located at their connecting portion for mutual connection. When the apparatus is to be reused, the toner and developing frames are readily separated by removing the connecting face pair even where the connecting face pair formed at the connecting portion of the toner frame and developing frame had been connected by welding or whatever. The toner frame and developing frame can be reconnected by welding again the remaining connecting faces at their connecting portions.
