Abstract
A cartridge set in a main body of an image forming apparatus including a developer roller positioned opposite a photosensitive member and a frame including the developer roller and in contact with an urging unit, wherein the urging unit is structured to urged the developer roller towards the photosensitive member, also the urging unit is structured to transfer a voltage from a power supply unit to the developer roller.
Claims19
A cartridge attachable to and detachable from a main body of an image forming apparatus comprising:
- a developer roller configured to face a photosensitive member;
- and
- a frame including the developer roller and in contact with an urging unit, wherein the urging unit is configured to urge the developer roller towards the photosensitive member, further wherein the urging unit is configured to transfer a voltage from a power supply unit to the developer roller.
An image forming apparatus comprising:
- a main body;
- and
- a cartridge attachable to and detachable from the main body,
- the cartridge including:
- a frame;
- and
- a developer roller disposed at the frame, the developer roller configured to face a photosensitive member;
- an urging unit disposed at the frame and configured to generate an urging force that urges the developer roller toward the photosensitive member, further wherein the urging unit is electrically connected to a power supply unit.
An image forming apparatus comprising:
- a main body;
- and
- a cartridge attachable to and detachable from the main body,
- the cartridge including:
- a frame;
- and
- a developer roller disposed at the frame, the developer roller configured to face a photosensitive member;
- an urging unit disposed at the main body and configured to generate an urging force that urges the developer roller toward the photosensitive member, further wherein the urging unit is electrically connected to a power supply unit.
A developer cartridge comprising:
- a frame having a toner chamber that accommodates toner;
- a developer roller disposed at the frame and exposed outward from the frame;
- a developer electrode disposed at the frame and electrically connected to the developer roller, wherein the developer electrode further includes an urging member urging the frame so that the developer roller moves in a direction outward from the frame.
