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.

Developing device and image forming apparatus including the same

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.

Developing device for a printer

Developing apparatus for printer

A charging apparatus including a charging tube which has an outer surface contacting a photoconductive medium and electrically charges a surface of the photoconductive medium, a shaft which is disposed in the charging tube and to which a charging voltage is applied, and a conductive member which is connected to the shaft and contacts an inner surface of the charging tube. A friction coefficient between the conductive member and the inner surface of the charging tube may be less than a friction coefficient between the photoconductive medium and the outer surface of the charging tube, so that a slip phenomenon of the charging tube is prevented.
