Abstract:
Disclosed is a development cartridge attachable/detachable to/from a main body of an image forming apparatus. The development cartridge includes at least a photosensitive drum to form an electrostatic latent image thereon or a developer roller to develop the electrostatic latent image by supplying a developer to the photosensitive drum, a housing to support the at least one photosensitive drum or the developer roller. A developer roller gear may be provided on a rotation shaft of the developer roller to connect to a driving gear of the main body when the development cartridge is attached to the main body, and a driven coupler provided at an end of the photosensitive drum to couple to a driving coupler located coaxially with the driving gear in the main body, based on shaft coupling when the development cartridge is attached to the main body.

Claim (Index 1):
A development cartridge attachable/detachable to/from a main body of an image forming apparatus, the development cartridge comprising:\n a photosensitive drum to form an electrostatic latent image on the photosensitive drum; a developer roller to develop the electrostatic latent image by supplying a developer to the photosensitive drum, the developer roller including a rotatable shaft; a housing to support the photosensitive drum and the developer roller; a developer roller gear provided on the rotatable shaft of the developer roller to connect to a driving gear of a driving coupler located coaxially with the driving gear in the main body when the development cartridge is attached to the main body; and a driven coupler provided at an end of the photosensitive drum to couple based on shaft coupling to the driving coupler located coaxially with the driving gear in the main body when the development cartridge is attached to the main body.
