PROBLEM TO BE SOLVED: To provide a cartridge which can be further miniaturized.SOLUTION: A developing cartridge comprises: a cartridge frame 31 including a left wall 36L and a right wall 36R horizontally arranged to face each other at an interval; a developer coupling 61 for receiving drive force from the outside; and a new product detection gear 82 to be detected by external detection means. In the developing cartridge, the developer coupling 61 is arranged on a left side of the left wall 36L and the new product detection gear 82 is arranged on a right side of the right wall 36R. The drive force input to the developer coupling 61 is transmitted to the new product detection gear 82 via an agitator 80 to be arranged between the left wall 36L and the right wall 36R. |
