Patent number: 10289062Abstract: 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.Type: GrantFiled: March 1, 2018Date of Patent: May 14, 2019Assignee: HP PRINTING KOREA CO., LTD.Inventors: Young Chae Kim, Junhui Kim, Jin-Hong Kim, Ji-Won Moon, Yun Kyu Shim, Sungwook Kang, Sunggi Kim
