Abstract
A developing cartridge includes: a cartridge containing a developer and including a first side wall and a second side wall positioned opposite to each other along a first direction; a power reception member configured to receive a driving power and positioned at the first side wall; a developing roller rotatable about a first axis extending in the first direction; and an activation member including a movable member and a detection protrusion positioned at the second side wall. The movable member rotates around a second axis in a second direction, the first direction and the second direction intersect with each other, and the detection protrusion moves as the movable member moves.
