Title:
DEVELOPING CARTRIDGE
Document Type and Number:
Japanese Patent JP2022011443
Kind Code:
A
Abstract:
To provide a developing cartridge which can make an input joint hardly come off from a coupling even if the cartridge rotates either clockwise or anticlockwise.SOLUTION: A coupling 22 can rotate clockwise D1 and anticlockwise D2, and has a recess 22A. The recess 22A has a first face 221 for receiving a rotation drive force when rotating clockwise, and a second face 222 for receiving the rotation drive force when rotating anticlockwise. The first face 221 and the second face 222 have second axes A2, and are inclined so that a distance from a plane HM which passes through a middle point between the first face 221 and the second face 222 becomes long as progressing toward a bottom face 224. When rotating clockwise D1, a force progressing toward the bottom face 224 acts on an input joint 7 by the inclination of the first face 221. When rotating anticlockwise D2, a force progressing toward the bottom face 224 acts on the joint 7 by the inclination of the second face 222.SELECTED DRAWING: Figure 17
