Abstract:
1. A cartridge configured to be removably mounted in a main body of an image forming apparatus, the cartridge comprising: a housing including an elastic urging portion integrally formed therein; a first rotating body including a detection target portion configured to be detectable by detecting means of the main body of the image forming apparatus, the first rotating body being provided at the housing such that the first rotating body is rotatable relative to the housing, the first rotating body including a transfer portion configured to rotate the first rotating body when a driving force is applied and a non-transfer portion configured to disable rotation of the first rotating body; and a second rotating body provided at the housing such that the second rotating body is rotatable relative to the housing, the second rotating body being able to transfer driving force input from the main body of the image forming apparatus to the first rotating body, wherein, when the transfer portion opposes the second rotating body, the first rotating body is configured to rotate upon receiving the driving force from the second rotating body, and, when the non-transfer portion opposes the second rotating body, the driving force from the second rotating body is not transferred to the first rotating body, wherein the first rotating body is rotatable between a first position and a second position, the first position being a position in which the detection target portion is detectable by the detecting means and the transfer portion opposes the second rotating body, the second position being a position in which the detection target portion is undetectable by the detecting means and the non-transfer portion opposes the second rotating body, wherein when the first rotating body is in the first position, the elastic urging portion, is configured to contact the first rotating body and impart rotational force so as to urge at least a portion of the transfer portion to be opposed to the second rotating body, and when the first rotating body is in the second position, the elastic urging portion is configured to contact the first rotating body and regulate a rotation of the first rotating body in a rotational direction so as to cause the non-transfer portion and the second rotating body to oppose each other.
