Abstract

A developing cartridge may include a housing including an outer surface, a small-diameter gear, a large-diameter gear, a first gear, and a moving member. The small-diameter gear may include a first engaging portion positioned on at least a portion of a peripheral surface of the small-diameter gear. The large-diameter gear may be positioned farther from the outer surface than the small-diameter gear from the outer surface. The large-diameter gear may be rotatable together with the small-diameter gear. The first gear may include a second engaging portion, a first end surface, a second end surface, and at least one protrusion. The moving member may include a contact portion configured to move the moving member from one position to another position in a state where the contact portion is in contact with the protrusion.
