A toner cartridge including a container body having a discharge opening. A drive transmitting member is fixedly coupled with the container body near the discharge opening. The drive transmitting member is sized and shaped to transmit rotational movement to the container body. A collar is moveably coupled along the container body, and the collar closes the discharge opening in a first position, and opens the discharge opening in a second position. The cartridge further includes, in one example, a biasing element sized and shaped to bias the collar toward the first position. In another example, the drive transmitting member includes at least one deflectable support member, and the deflectable support member includes a ramped drive element. The ramped drive element includes a first ramp face, a second ramp face, and at least one driving face. Optionally, the first and second ramp faces are sloped with respect to the support member.
