Abstract: A developing cartridge is disposed in an image forming apparatus. The developing cartridge includes a developing portion; a toner storing portion; a partition wall positioned between the developing portion and the toner storing portion and provided with a toner supply section; a first agitating member inside the developing portion; and a second agitating member inside the toner storing portion, wherein at least one of the first agitating member and the second agitating member comprises an elastic member to be in contact with the partition wall.

Abstract: A developing device includes: a photosensitive body on which an electrostatic latent image is formed; a development chamber; a development roller that faces the photosensitive body and transfers toner to the electrostatic latent image; a supply roller that supplies toner from the development chamber to the development roller; and an agitating member that is disposed under the supply roller in the development chamber and agitates the toner that is in the development chamber.

Abstract: Provided is a developer cartridge attachable to and detachable from a main body of an image forming apparatus. The developer cartridge includes: a memory unit including a contact portion moved to a first position hidden inside the developer cartridge and a second position protruding outside the developer cartridge; an operating portion configured to move the contact portion to the first position and the second position; an outlet configured to discharge a developer; and a first shutter having an opening position and a closing position for opening and closing the outlet and moved to the closing position and the opening position when the contact portion is moved to the first position and the second position.

Abstract: A cartridge that is attached to or detached from a main body of an image forming apparatus. The cartridge includes a memory unit that includes a contact portion via which the cartridge is connected to the main body and is connected to the main body to transmit information of the cartridge to the main body. The contact portion is moved to a first position at which the contact portion is hidden inside the cartridge and a second position at which the contact portions is protruded out of the cartridge to be connected to a connection portion provided in the main body.

Abstract: A developing device that attaches/detaches to/from a main body of an image forming apparatus includes a first frame that supports a photosensitive member, a second frame that supports a developing roller, and a connecting bracket in which a fixed supporter couples to a side portion of the first frame, a flexible supporter that couples to a side portion of the second frame, and an elastic arm connecting the fixed supporter and the flexible supporter to each other to provide an elastic force that may elastically bias the developing roller toward the photosensitive member, are integrally formed.

Abstract: A developing roller including a housing containing toner; and a developing roller installed in the housing and supplies the toner to an electrostatic latent image formed on a photoconductor, the developing roller including a cylindrical unit in the form of a hollow pipe and a power transmission unit connected to one end of the cylindrical unit and connected to a power transmission member for rotating the developing roller. Both ends of the cylindrical unit are supported by the housing and the power transmission unit is not restricted by the housing. Both ends of the cylindrical unit are supported by the housing and the power transmission unit is not restricted by the housing.
