The package has an used developer cartridge, a packing case and cushioning
members. The packing case is configured with a upper surface that can be
opened. When packed in the packing case, the developer cartridge is
accommodated in the cushioning members so that the developing roller is
positioned vertically above the toner-extracting hole. Recessed parts are
formed in the cushioning members, respectively. One recessed part is
shaped to closely fit over the upper surface of the developer cartridge.
The other recessed part is shaped to fit closes over the lower surface of
the developer cartridge. The recessed parts accommodate the developer
cartridge so that the developer cartridge has no play therein.
