Cartridge having photosensitive body cartridge and developer cartridge

摘要

A developer cartridge includes: a first rotary body having at least one detected part; and a second rotary body. The first rotary body is configured to rotate between a first position, in which a transmission part is disposed opposite the second rotary body, and a second position, in which a non-transmission part is disposed opposite the second rotary body. The first rotary body includes a contacted part. A photosensitive body cartridge includes a moving member. When the moving member is in a third position, the moving member contacts the contacted part of the first rotary body disposed in the second position, causing the first rotary body to rotate to the first position. Thereafter, in association with rotation of the first rotary body, the moving member moves to a fourth position, in which the moving member is unable to contact the contacted part.

主权项

1. A process cartridge comprising:
a first cartridge provided with a gear and a detection gear, the detection gear being configured to rotate around a first axial line extending in a first direction, and to move between a first position, in which the detection gear is capable of receiving drive force from the gear, and a second position, the detection gear comprising:
a disc-shaped body part, andat least one protrusion protruding from the body part in the first direction and configured to rotate together with the body part, the at least one protrusion being configured to engage with an engaging part; and a second cartridge configured to be detachably attached to the first cartridge, the second cartridge being provided with the engaging part that is configured to engage with the detection gear in the second position, thereby moving the detection gear from the second position to the first position, the engaging part being configured to move from a third position to a fourth position such that:
a part of the engaging part is disposed within a moving path of the at least one protrusion when the engaging part is in the third position, andthe part of the engaging part is disposed outside the moving path of the at least one protrusion when the engaging part is in the fourth position, wherein, when the detection gear is in the second position and the second cartridge is not attached to the first cartridge, the detection gear does not receive drive force from the gear.
