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.
