Abstract
An image forming apparatus including: a toner cartridge to store toner; a developer to develop an image on a printing medium using the toner from the toner cartridge; and a waste toner container to store waste toner removed from the developer, wherein the waste toner container includes: a first transporting unit provided near a waste toner inlet; and a second transporting unit provided at a point where the waste toner transported by the first transporting unit falls to transport the waste toner to a farthest point from the waste toner inlet.
Claims43
A waste toner container to receive and store waste toner removed from a developer of an image forming apparatus, the waste toner container comprising:
- a first transporting unit provided at a first point inside the waste toner container to transport the waste toner;
- and
- a second transporting unit provided at a second point inside the waste toner container, different from the first point, to transport the waste toner, the second transporting unit including a rib to collect at least some of the waste toner transported by the first transporting unit,
- wherein the first point is at a higher position from a bottom surface of the waste toner container than the second point.
An image forming apparatus comprising:
- a developer to develop an image on a printing medium using toner from a toner cartridge;
- and
- a waste toner container to store waste toner removed from the developer, the waste toner container comprising:
- a first transporting unit provided at a first point inside the waste toner container to transport the waste toner away from a waste toner inlet;
- and
- a second transporting unit provided at a second point inside the waste toner container to transport the waste toner, transported by the first transporting unit, away from the waste toner inlet, the second transporting unit including a second transporting unit rib to collect at least some of the waste toner transported by the first transporting unit,
- wherein, the first point is at a higher position from a bottom surface of the waste toner container than the second point.
A method of storing waste toner of an image forming apparatus, the method comprising:
- receiving the waste toner through a waste toner inlet;
- transporting the waste toner away from the waste toner inlet with a first transportation force by a first transporting unit;
- and
- transporting the waste toner, transported with the first transportation force, further away from the waste toner inlet with a second transportation force by a second transporting unit, the second transporting unit including a rib to collect at least some of the waste toner transported by the first transporting unit.
A waste toner container to receive and store waste toner removed from a developer of an image forming apparatus, the waste toner container comprising:
- a first transporting unit provided at a first point inside the waste toner container to transport the waste toner;
- and
- a second transporting unit provided at a second point inside the waste toner container, different from the first point, to transport the waste toner, the second transporting unit including a second transporting unit rib to collect at least some of the waste toner transported by the first transporting unit,
- wherein the first point is at a higher position from a bottom surface of the waste toner container than the second point.
