Abstract:
To provide a developing cartridge that has new gear structure for specifying specifications of the developing cartridge.SOLUTION: The developing cartridge comprises: a housing; a first gear (a second agitator gear 100) that is rotatable with respect to a first shaft; a second gear (a detection gear 200) that is rotatable with respect to a second shaft, and is rotatable from a first location to a second location together with the first gear when engaging with the first gear; a cover (a second gear cover 31); a link 280 that is rotatable together with the second gear, and can oscillate with respect to the second gear; and an energizing member (a spring 300). The energizing member is the energizing member that engages with the second gear and the link 280, and has a first state where, when the second gear is at the first location, the energizing member is elastically deformed and a tip part 281 of the link 280 contacts with the cover, and a second state where, when the second gear is at the second location, the contact of the tip part 281 with the cover is released, and the link 280 oscillates with respect to the second gear due to resilience of the energizing member.SELECTED DRAWING: Figure 13
