## Abstract

A developing cartridge includes a first gear, a second gear, and a protrusion. The first gear is rotatable about a first axis extending in a predetermined direction. The second gear is configured to engage with the first gear and rotatable about a second axis extending in the predetermined direction. The protrusion extends in the predetermined direction and circularly movable together with rotation of the second gear. The first gear is movable in a direction away from the second gear from a first position to engage with the second gear to a second position to disengage from the second gear.

## Claims

### Claim 1

A developing cartridge comprising:
a first gear rotatable about a first axis extending in a predetermined direction; and
a second gear configured to engage with the first gear and rotatable about a second axis extending in the predetermined direction, the second gear including a protrusion extending in the predetermined direction, the protrusion being circularly movable together with rotation of the second gear,
wherein the first gear is movable in a direction away from the second gear from a first position in which the first gear engages with the second gear to a second position in which the first gear disengages from the second gear, and
wherein the first gear is movable from the first position to the second position in a direction crossing the predetermined direction.

### Claim 2 (depends on 1)

The developing cartridge according to claim 1, further comprising a stopper configured to fix the first gear at the second position.

### Claim 3 (depends on 1)

The developing cartridge according to claim 1, further comprising a housing configured to accommodate developing agent.

### Claim 4 (depends on 3)

The developing cartridge according to claim 3, further comprising:
a gear cover covering at least a portion of the first gear and the second gear, the gear cover having an opening,
wherein the first gear and the second gear are positioned between the gear cover and the housing in the predetermined direction, and
wherein, when the second gear in engagement with the first gear rotates, the protrusion passes through the opening in a state where the protrusion is exposed via the opening.

### Claim 5

A developing cartridge comprising:
a housing configured to accommodate developing agent;
a first gear rotatable about a first axis extending in a predetermined direction;
a second gear configured to engage with the first gear and rotatable about a second axis extending in the predetermined direction;
a protrusion extending in the predetermined direction and circularly movable together with rotation of the second gear;
an agitator including an agitator shaft extending in the predetermined direction, the agitator configured to agitate the developing agent; and
a connector connected to the agitator shaft and rotatable with the agitator shaft, the connector including a groove,
wherein the first gear is movable in a direction away from the second gear from a first position in which the first gear engages with the second gear to a second position in which the first gear disengages from the second gear,
wherein the first gear includes an engagement portion protruding in the predetermined direction toward the connector, the engagement portion extending in a radial direction of the first gear, and
wherein the first gear is slidably movable relative to the connector along with the groove and the first gear is movable in the direction away from the second gear, in a state where the engagement portion engages the groove.

### Claim 6 (depends on 5)

The developing cartridge according to claim 5, wherein the engagement portion is another protrusion, and
wherein the first gear is slidably movable relative to the connector along with the groove and the first gear is movable in the direction away from the second gear, in a state where the protrusion is fitted into the groove.
