Abstract: A container for a toner cartridge includes a hollow main body defining a longitudinal central axis. The main body has a first section near a rear end thereof, a second section near a front end thereof, a connecting section between the first and second sections, a longitudinal rib extending from the first section to the second section via the connecting section. The radii of cross sections of the first and second sections respectively gradually increase toward the front end of the main body. The longitudinal rib has a third guiding surface defining with the central axis a distance shorter than the radius of a cross section of the connecting section. The container can effectively move the toner accommodated inside the container from the rear end toward the front end. A mold for the container is easy to manufacture, resulting in cost reduction in manufacturing.

Abstract: A toner cartridge includes a casing provided at a bottom side thereof with an outlet, a sliding member slidably mounted on the casing, and a retaining member pivotally mounted on the casing. The sliding member is movable relative to the casing between a first position where the outlet is closed by the sliding member and a second position where the outlet is opened. The retaining member is pivotable relative to the casing between a third position where the retaining member is engaged with the sliding member to lock the sliding member at the first position, and a forth position where the retaining member is disengaged from the sliding member such that the sliding member is moveable to the second position to open the outlet. The toner cartridge has the advantage of preventing leakage of toner due to unintentional movement of the sliding member.

Abstract: A lid to selectively plug or unplug a discharge mouth of a toner container mountable to an image forming apparatus for replenishing a toner.
