1. A developing cartridge comprising:
- a developing roller rotatable about a first axis extending in an axial direction;
a coupling for rotating the developing roller, the coupling being rotatable about a second axis extending in the axial direction;
a shaft rotatably supporting the coupling; and
a clutch rotatable together with the coupling about the shaft in a case where the coupling rotates in a first rotational direction, wherein, in a case where the coupling rotates in a second rotational direction opposite to the first rotational direction, the clutch engages with a portion of the shaft and the clutch and the coupling do not rotate.

Abstract
A developing cartridge includes: a developing roller; a coupling for rotating the developing roller; a shaft; and a clutch. The developing roller is rotatable about a first axis extending in an axial direction. The coupling is rotatable about a second axis extending in the axial direction. The shaft rotatably supports the coupling. The clutch is rotatable together with the coupling about the shaft in a case where the coupling rotates in a first rotational direction. In a case where the coupling rotates in a second rotational direction opposite to the first rotational direction, the clutch engages with a portion of the shaft and the clutch and the coupling do not rotate.
