1. A cartridge comprising:
a developing roller rotatable about a developing axis extending in a first direction;
a frame configured to accommodate developing material therein, the frame having a first end portion and a second end portion separated from the first end portion in the first direction, the frame having a third end portion and a fourth end portion separated from the third end portion in a second direction, the developing roller being positioned at the third end portion;
a coupling rotatable about a coupling axis extending in the first direction, the coupling being positioned at the first end portion, the coupling including a coupling gear;
an electrode electrically connected to the developing roller, the electrode being positioned at the second end portion;
an idle gear rotatable about an idle gear axis extending in the first direction, the idle gear meshing with the coupling gear, the idle gear being positioned at the first end portion;
an agitator rotatable about an agitator axis extending in the first direction;
an agitator gear rotatable with the agitator, the agitator gear meshing with the idle gear, the agitator gear being positioned at the first end portion, and
a slide plate linearly movable relative to the frame in association with rotation of the agitator gear, the slide plate linearly movable between a first position and a second position in the second direction,
wherein a first distance between the developing roller and the slide plate in the second direction in a state where the slide plate is positioned at the first position is greater than a second distance between the developing roller and the slide plate in the second direction in a state where the slide plate is positioned at the second position.
