Toner cartridge and drum cartridge for receiving the toner cartridge therein

A toner cartridge comprising:

• a generally cylindrical outer pipe having longitudinally opposed first and second end portions, the outer pipe having at least one first opening between said opposed end portions;
• and
• a generally cylindrical inner pipe inserted into said outer pipe, the inner pipe having longitudinally opposed third and fourth end portions and at least one second opening between the third and fourth and portions, the fourth end portion having a knob closing the fourth end portion, the knob rotating the inner pipe with respect to the outer pipe, the first opening being out of alignment with the second opening when the inner pipe is rotated to a first rotational position with respect to the outer pipe and being in alignment with the second opening when said inner pipe is rotated to a second rotational position;
• wherein the inner pipe rotates with respect to the outer pipe when the knob rotates with respect to the outer pipe;
• and wherein the knob has a substantially radially projecting lever, the lever has at least an arrow indicative of one of a direction of rotation of the inner pipe relative to the outer pipe toward the first rotational position and a direction of rotation of the inner pipe relative to the outer pipe toward the second rotational position.
