Abstract: A developing unit for an imaging device, which includes a toner developing member, a toner hopper, and a toner cartridge. The toner hopper includes a cartridge installation hole into which the toner cartridge may be installed. The toner cartridge includes an inner sleeve member that stores toner in its interior and an outer sleeve member disposed around the outer circumference of the inner sleeve member and capable of relative rotation with it. The inner sleeve member includes a first opening in its surface which faces downward during installation into the imaging device, and the outer sleeve member includes a second opening in its surface which may be aligned with the first opening. The toner cartridge may only be removed from the toner hopper when the second opening in the outer sleeve member is rotated 180 first opening in the inner sleeve member, thereby preventing the inadvertent spillage of toner.

Abstract: In a toner cartridge for supplying toner to the developing unit in a xerographic image forming apparatus, the casing containing toner has two toner discharge openings sealed prior to installation by a sealing film having a sealing portion peel-separably affixed to the casing around the toner discharge openings, as well as a peel-separating leader portion. The sealing film overlaps itself, having open opposite lateral edges. The toner cartridge is fitted with retaining elements affixed to the casing along opposite lateral edges of the toner discharge openings, for covering the open opposite lateral edges of the sealing film. An installation seat having a toner-disgorging opening corresponding to the toner discharge openings is fixed to the end of the toner cartridge casing. The installation seat includes pressing elements therein disposed over the retaining elements for maintaining external pressure on the retaining elements.

Abstract: A toner supply device in which a toner cartridge can smoothly be inserted and removed. The toner supply device includes a toner supply device main body capable of removably setting the toner cartridge to a setting position. The toner supply device main body includes a guide tray for guiding the toner cartridge along an insertion in direction when the toner cartridge is inserted to and pulled out from the setting position. Thus, the toner cartridge can smoothly be inserted and removed. The guide tray can assume a guide posture for guiding the insertion and removal of the toner cartridge, and a retreat posture where the guide tray is being retreated to a retreat position.

Abstract: A developing unit (12) for an imaging device, which includes a toner developing member (33), a toner hopper (34), and a toner cartridge (35). The toner hopper (34) includes a cartridge installation hole (36) into which the toner cartridge (35) may be installed. The toner cartridge (35) includes an inner sleeve member (51) that stores toner in its interior and an outer sleeve member (52) disposed around the outer circumference of the inner sleeve member (51) and capable of relative rotation with it. The inner sleeve member (51) includes a first opening (53) in its surface which faces downward during installation into the imaging device, and the outer sleeve member (52) includes a second opening (54) in its surface which may be aligned with the first opening (53). The toner cartridge (35) may only be removed from the toner hopper (34) when the second opening (54) in the outer sleeve member (52) is rotated 180 DEG with respect to the first opening (53) in the inner sleeve member (51), thereby preventing any inadvertent spillage of toner.

Abstract: A toner cartridge (24) is disclosed which includes a case (25) having two toner discharge openings (26, 27) through the surface connected to a toner hopper (23), two sealing films (28, 29), and a reeling shaft (36). The sealing films (28, 29) are removably adhered to the portion adjacent to the toner discharge openings (26, 27), and seal the toner discharge openings (26, 27). The reeling shaft (36) is rotatably supported by the case (25), and allows the plurality of sealing films (28, 29) to be removed from the toner discharge openings (26, 27) during toner cartridge installation by reeling the sealing films (28, 29) around the reeling shaft (36). At least one of the plurality of sealing films (28, 29) is longer than the others, and is attached to the reeling shaft (36) in a direction opposite that of the others. This arrangement allows the timing of removal of the sealing films (28, 29) to be shifted, thereby reducing the amount of torque required for their removal.

Abstract: A toner cartridge comprises a container body (4) having a tubular wall (16) with a longitudinally extending toner discharge opening (26) formed therein, and opposite end walls (20,22) closing the longitudinally opposite end portions of the tubular wall (16); a toner accommodated in the container body (4); and a sealing member (6) unsealably sealing the toner discharge opening (26) of the container body (4). The inner surface of at least one of the opposite end walls (20,22) of the container body extends, at the angle of inclination which is larger than the angle of repose of the toner accommodated in the container body, longitudinally outwardly from the edge substantially coinciding with one longitudinal edge of the toner discharge opening. Alternatively, the inner surface of at least one of the opposite end walls (20,22) of the container body (4) extends inwardly and longitudinally outwardly, at the angle of inclination which is larger than the angle of repose of the toner accommodated in the container body, from the outer peripheral edge thereof, and one longitudinal edge of the toner discharge opening is substantially conformed to the outer peripheral edge of the inner surface of that one of the opposite end walls of the container body.
