A system for an electrophotographic image forming device includes a basket including a plurality of positioning slots each including cartridge datum locators that position a plurality of toner cartridges relative to the basket. A first guide rail and a second guide rail, each movable between a raised position and a lowered position, raise and lower the basket when the first and second guide rails move between the raised and lowered positions. In the raised positions the first and second guide rails support the basket permitting the basket to slide along the first and second guide rails into and out of the image forming device. When the first and second guide rails are in the lowered positions basket datum locators within the image forming device support the basket and position the basket relative to the image forming device in order to position the toner cartridges relative to the image forming device.

A system for an electrophotographic image forming device includes a basket insertable into and extendable out of the image forming device. The basket includes a plurality of positioning slots each configured to receive a corresponding toner cartridge of a plurality of toner cartridges. The basket includes a cartridge latching assembly configured to apply a hold-down force on each toner cartridge to rigidly hold each toner cartridge against corresponding datums of the basket. A basket latching assembly in the image forming device is configured to apply a hold-down force on the basket when the basket is inserted into the image forming device to rigidly hold the basket against corresponding datums of the image forming device for positioning the plurality of toner cartridges in respective operational positions within the image forming device with only the cartridge latching assembly of the basket directly applying hold-down forces on the plurality of toner cartridges.

A toner refilling interface structure including a toner cartridge, an installation portion, a first toner inlet portion, an inlet shutter, and a locking member. The toner cartridge including a discharge shutter located in or coupled to a body and to switch to a closed position at which a first toner discharge portion of the body is closed and to switch to a discharge position at which the first toner discharge portion is open. The toner cartridge is rotatable about a first rotation axis. The first toner inlet portion is provided in the installation portion to receive toner from the toner cartridge. The inlet shutter is provided in the installation portion to switch to an inflow position at which the first toner inlet portion is open, from a blocked position at which the first toner inlet portion is blocked, by a first rotation of the toner cartridge from an installation position to a first angular position The locking member is provided in the toner cartridge and to lock the discharge shutter at the closed position during the first rotation of the toner cartridge.

The basket includes a cartridge latching assembly configured to apply a hold-down force on each toner cartridge to rigidly hold each toner cartridge against corresponding datums of the basket. A basket latching assembly in the image forming device is configured to apply a hold-down force on the basket when the basket is inserted into the image forming device to rigidly hold the basket against corresponding datums of the image forming device for positioning the plurality of toner cartridges in respective operational positions within the image forming device with only the cartridge latching assembly of the basket directly applying hold-down forces on the plurality of toner cartridges.

A system for an electrophotographic image forming device includes a basket having a first side, a second side and a plurality of positioning slots extending between the first side and the second side, each positioning slot is configured to receive a corresponding toner cartridge. Each positioning slot includes a first latch at the first side of the basket and a second latch at the second side of the basket. Each of the first and second latches is independently pivotable between a latched position for applying a hold-down force on a respective end portion of a corresponding toner cartridge positioned in a corresponding positioning slot of the plurality of positioning slots to rigidly hold the corresponding toner cartridge against datums of the basket and an unlatched position to release the corresponding toner cartridge permitting removal of the corresponding toner cartridge from the basket.

A system for an electrophotographic image forming device includes a basket for holding multiple toner cartridges. A guide rail assembly operatively connected to an access door moves between a raised position and a lowered position to raise and lower the basket when the access door moves between an open position and a closed position. The basket is slidable along the guide rail assembly into and out of the image forming device when the guide rail assembly is in the raised position, and is in an operational position within the image forming device when the guide rail assembly is in the lowered position. A rail lock mechanism locks the access door in the open position when the guide rail assembly is in the raised position and the basket is extended out of the image forming device and unlocks the access door from the open position when the basket is inserted.

A developer container includes a plurality of components combined together to form a space to store a developer. The plurality of components includes a first component and a second component. The developer container further includes a sealant to bond the first component and the second component, and a position regulator to regulate relative positions of the first component and the second component so as to maintain a distance between an adhesion portion of the first component and an adhesion portion of the second component.

A toner refilling interface structure including a toner cartridge, an installation portion, a first toner inlet portion, an inlet shutter, and a locking member. The toner cartridge including a discharge shutter located in or coupled to a body and to switch to a closed position at which a first toner discharge portion of the body is closed and to switch to a discharge position at which the first toner discharge portion is open. The toner cartridge is rotatable about a first rotation axis. The first toner inlet portion is provided in the installation portion to receive toner from the toner cartridge. The inlet shutter is provided in the installation portion to switch to an inflow position at which the first toner inlet portion is open, from a blocked position at which the first toner inlet portion is blocked, by a first rotation of the toner cartridge from an installation position to a first angular position The locking member is provided in the toner cartridge and to lock the discharge shutter at the closed position during the first rotation of the toner cartridge.
