Abstract
A process cartridge of an image forming device has a photosensitive body unit including a photosensitive body and a photosensitive body driving part. The photosensitive body driving unit has a photosensitive body gear formed on a photosensitive body shaft. An electrostatic latent image is formed on the photosensitive body. A developing unit includes developing roller developing the electrostatic latent image and a developing driving part. The developing driving part has a developing roller gear formed on a developing roller shaft. A housing integrates the photosensitive body unit and the developing unit into a single module. The developing driving part includes a driving member protruding outside of the housing and transmitting a driving force from the outside. The developing roller of the developing unit may be driven only when necessary, and the process cartridge may be mounted to the image forming device body without requiring a coupling device.
