<p>A toner cartridge includes an outer pipe (1), inner pipe (2) inserted into the outer pipe (1), and cap (5) fitted over the inner pipe (2). The outer pipe (1) and inner pipe (2) are of a long, hollow cylinder shape and are formed with a plurality of first and second openings (1b, 2b), respectively, The inner pipe (2) has at one end thereof a toner-filling opening (2c) and an annular flange eccentric with respect to the hollow cylinder, and at the other end thereof a knob (4) that closes the longitudinal end of the hollow cylinder and abuts the outer pipe (1). The first openings (1b) are not aligned with the second openings (2b) when the inner pipe (2) is at a first rotational position and are aligned when the inner pipe (1) is at a second rotational position. A sealing member (3) is mounted to the inner pipe (2) encircling the second openings (2b) and has third openings (3b) aligned with the second openings (2b). The sealing member (3) not only seals the gap between the inner pipe (2) and the outer pipe (1) but also holds the inner pipe (2) eccentric with respect to the outer pipe (1). The outer pipe (1) has at least one flange (1a) which radially outwardly extends from the outer pipe (1) and longitudinally extends along the outer pipe (1). The flange (1a) has a plurality of ribs (1d) on one side thereof. The toner filling-opening (2c) has the same diameter as that of the hollow cylinder. <IMAGE></p> |
