Abstract
A developing cartridge includes: a developing roller rotatable about an axis extending in a first direction; a casing having a first outer surface and a second outer surface spaced apart from each other in the first direction; a first separation member positioned at the first outer surface; and a second separation member positioned at the second outer surface. The second separation member has a first end portion configured to contact a body-side cam of an image-forming apparatus. In a state where a drum cartridge is attached to an apparatus body of the image-forming apparatus in an attached state of the developing cartridge to the drum cartridge, the first separation member is pressed by a drum cam of the drum cartridge, and the first end portion of the second separation member is pressed by the body-side cam to move the developing roller from a contacting position to a separated position.
