Title:
DEVELOPMENT CARTRIDGE
Document Type and Number:
WIPO Patent Application WO/2018/198605
Kind Code:
A1
Abstract:
The purpose of the present invention is to prevent a coupling from rotating in a second rotational direction opposite a first rotational direction. A development cartridge 10 comprises: a development roller 12 rotatable about a first axis 12X that extends in an axial direction; a coupling 22 rotatable about a second axis 22X that extends in the axial direction, the coupling 22 serving to rotate the development roller 12; a shaft 27B that supports the coupling 22 rotatably; and a clutch 40 that is rotatable about the shaft 27B together with the coupling 22 when the coupling 22 is rotated in a first rotational direction D1, and that engages with a portion of the shaft 27B when the coupling 22 is rotated in a second rotational direction D2 opposite the first rotational direction D1 so that the clutch 40 and the coupling 22 do not to rotate in the second rotational direction D2.
