Abstract
The present disclosure provides a developing cartridge, detachably mounted on a photosensitive drum cartridge which is detachably mounted inside an image forming apparatus and includes a drum holder and a photosensitive drum. At least one sidewall of the drum holder is provided with a supporting part. The developing cartridge includes a frame and a developing roller. At least one side-end surface of the frame is provided with a supported element. When the developing cartridge and the photosensitive drum cartridge are mounted, the supported element receives a force applied by a force-applying component of the image forming apparatus, such that the developing roller is maintained pressed against the photosensitive drum. The angle between the direction of the force and the normal direction of the contact interface between the supported element and the supporting part is larger than or equal to the friction angle between the supported element and the supporting part.
