Claims
- 1. An image formation apparatus comprising:
- a first case including means for removably inserting said first case into said apparatus,
- a second case including means for removably inserting said second case into said apparatus;
- said first and second cases being physically distinct from each other and located adjacent each other in said apparatus,
- said image formation apparatus including an image carrier on which electrostatic latent images are formed and developed by the use of toner;
- said first case including a cleaning means for removing residue toner from said image carrier;
- said second case comprising a developer module for applying toner to said image carrier and a residue toner collecting chamber for interconnecting with and for receiving residue toner from said cleaning means;
- said first and second cases further including interacting guide means and indexing means, respectively, for positioning said developer module with respect to said image carrier and for interconnecting said residue toner collecting chamber with said cleaning means in response to insertion of a said second case into said image forming apparatus containing said first case;
- means for inserting said second case only after said first case has been inserted;
- wherein said second case includes a cover, covering an opening in the chamber and said first case includes a cover; and
- means for opening said covers when said second case is inserted, so that said residue toner flows from said first case directly to said chamber.
- 2. The image formation apparatus of claim 1, further including,
- means for removably detaching said first and second case in said apparatus, so that when said second case is detached the developer module and said residue toner collecting chamber detach as a single unit.
- 3. The image formation apparatus of claim 1, wherein the first case has a first life of interchange and the second case has a second life of interchange.
- 4. The image formation apparatus according to claim 3 in which said first life of interchange is a life of said image carrier and said second life of interchange is a life of a developer contained in said developer module.
- 5. The image formation apparatus according to claim 4, in which said residue toner collecting chamber of said second case has a volume being capable of containing residue toner to be collected until the life of said developer module is over.
- 6. The image formation apparatus as claimed in claim 3, wherein said image carrier is a photosensitive body.
- 7. The image formation apparatus according to claim 6 in which said first life of interchange is a life of said photosensitive body and said second life of interchange is a life of a developer contained in said developer module.
