Abstract
A developing device usable with an image forming apparatus having a developer delivery device of an improved drive configuration. The developing device includes a developer storage unit, a rotating member arranged in the developer storage unit, and a plurality of developer delivery members arranged in an axial direction of the rotating member to be rotated around the rotating member upon receiving rotation power from the rotating member. A first power-transmission structure may be provided between at least one of the plurality of developer delivery members and the rotating member to allow slip therebetween.
Claims23
A developing device usable with an image forming apparatus, the developing device comprising:
- a developer storage unit;
- a first rotating member arranged in the developer storage unit;
- and
- a plurality of developer delivery members arranged in an axial direction of the first rotating member to be rotated around the first rotating member upon receiving rotation power from the first rotating member.
A developing device usable with an image forming apparatus, the developing device comprising:
- a housing having a developer storage unit defined therein;
- a first rotating member and a second rotating member arranged in the developer storage unit;
- and
- a first, second, and third developer delivery belts arranged in an axial direction of the first rotating member and rotatably supported by the first rotating member and the second rotating member,
- wherein at least one of the first, second, and third developer delivery belts is rotatable relative to the first rotating member.
A developing device usable with an image forming apparatus, comprising:
- a developer storage unit to store developer therein and having a predetermined width;
- a plurality of developer delivery members adjacent to each other and extending along the predetermined width within the developer storage unit;
- and
- a drive member to drive the plurality of developer delivery members to deliver developer along a lengthwise direction of the developed receiving chamber.
An image forming apparatus comprising a developing device, the developing device comprising:
- a developer storage unit;
- a first rotating member arranged in the developer storage unit;
- and
- a plurality of develop delivery members arranged in an axial direction of the first rotating member to be rotated around the first rotating member upon receiving rotation power from the first rotating member.
