A system for an electrophotographic image forming device according to one example embodiment includes a first replaceable unit having a first shutter movable between a closed position blocking an outlet port of the first replaceable unit and an open position unblocking the outlet port. A second replaceable includes an inlet port that is configured to receive toner from the outlet port of the first replaceable unit. The second replaceable unit includes a second shutter movable between a closed position blocking the inlet port and an open position unblocking the inlet port. A portion of the first shutter of the first replaceable unit is positioned to contact and move the second shutter of the second replaceable unit from the closed position of the second shutter to the open position of the second shutter during insertion of the first replaceable unit into the image forming device.

An image forming apparatus includes a developing device detachably mountable to an image forming apparatus; a supplying device including an accommodating portion for accommodating a developer supplied from a developer container accommodating the developer, the supplying device being effective to supply the developer accommodated in the accommodating portion into the developing device; a controller for controlling the supply of the developer from the supplying device into the developing device; a communicating portion provided in the supplying device, for fluid communication between the accommodating portion and the developing device; a seal provided at the communicating portion to hermetically confining the developer in the accommodating portion before an operation of image forming apparatus; and a removing portion for receiving a driving force from the image forming apparatus to wind the seal up to permit fluid communication between the accommodating portion and the developing device.

A system with a container including a protrusion, and a receiver to receive the container. The receiver includes a slide block that is movable relative to a body of the receiver, the slide block including two surfaces, a first surface, initially contacted by the protrusion of the container during insertion of the container into the receiver, having a first slope to resist movement of the container towards the receiver, and a second surface, subsequently contacted by the protrusion of the container during the insertion of the container into the receiver, having a second slope to interact with the protrusion of the container to assist movement of the container towards the receiver. This construction provides the user with a changing insertion force to indicate proper mounting of the container.

An electrophotographic image forming device includes a replaceable unit having a body with a toner reservoir. A drive element on a rear end of the body is unobstructed to mesh with a corresponding drive element in the image forming device. A toner outlet port is positioned on a bottom of the body near the rear end of the body. A latch catch is positioned on a first side of the body to receive a corresponding latch when the replaceable unit is installed in the image forming device. A latch actuator at the front end of the body is movable between a home position and a releasing position. A release handle at the front end of the body is operatively connected to the latch actuator such that actuation of the release handle causes the latch actuator to move from the home position to the releasing position to unlatch the body.

An image forming apparatus includes: a housing having an opening providing a first region and a second region; first and second covers for opening and closing the first and second regions, respectively; a drum cartridge detachably attachable to the housing in a first direction through the first region; and a toner cartridge. A part of the toner cartridge attached to the drum cartridge is movable between a first position and a second position. The toner cartridge is detachable from the drum cartridge attached to the housing through the second region in a second direction crossing the first direction when the first cover is closed, the second cover is opened, and the part of the toner cartridge is at the second position. The part of the toner cartridge is movable from the first position to the second position in a third direction crossing the first and second directions.

A toner container includes a toner accommodating portion, a discharge portion, a shutter, a sealing member, and a guiding portion. In a case where a direction from the toner accommodating portion toward the discharge portion in a rotational axis direction is a first direction, where a direction opposite to the first direction is a second direction, and where an end portion of the sealing member on a downstream side of the first direction is a first end portion, a downstream end portion of the guiding portion is positioned downstream of the first end portion of the sealing member with respect to the first direction. The downstream end portion of the guiding portion overlaps with the sealing member as viewed in the rotational axis direction, and includes an inclined surface inclined so as to approach the contact surface of the seal member as it goes in the second direction.

An image forming apparatus includes a main body housing and a process cartridge demountable from the main-body housing. The process cartridge includes a drum cartridge and a toner cartridge. The drum cartridge includes a photosensitive drum, a drum cleaner, an outlet with an outlet opening, an outlet shutter, and a lever. The lever is pivotable between a first position at which the lever places the outlet shutter closing the outlet opening and a second position at which the lever places the outlet shutter opening the outlet opening. When the lever is located at the first position, the process cartridge is demountable from the main-body housing. When the lever is located at the second position, the process cartridge is disabled to be demounted from the main-body housing.

Toner cartridge includes a housing, an agitator, an auger, a first protrusion, and a second protrusion. The housing includes a first toner accommodating portion having and a second toner accommodating portion. The auger is rotatable about a second axis extending in a first direction and is configured to convey toner from a first toner accommodating portion to the second toner accommodating portion. The first protrusion is positioned at a first side of the second toner accommodating portion. The first protrusion extends in the first direction. The second protrusion is positioned at a second side of the second toner accommodating portion and extends in the first direction.

A developer container includes a pouch, a communication member, and a cap. A marking including an arrowhead part and a parting line are formed on an outer peripheral surface of the cap. A rear end of the arrowhead part is disposed between a first position that is a position 45 upstream from a reference position in a direction of rotation and a second position that is a position 45 downstream in the direction of rotation. The rear end of the arrowhead part overlaps the parting line.

Disclosed is a developer storage container including a container body and a shutter. The container body has a developer discharge port and is capable of being changed in posture. The shutter is configured to sealingly close or open the developer discharge port, and includes a shutter body, a swingable member and a shaft displacement restriction portion. The shutter body has a sealing surface for sealingly closing the developer discharge port, and a pair of bearing portions. The swingable member has a pair of shaft portions each pivotally supported by a respective one of the pair of bearing portions. The swingable member is swingable between a restriction position where it restricts a sliding movement of the shutter, and a permission position where it permits the sliding movement of the shutter. The shaft displacement restriction portion is configured to restrict an axial movement of the pair of shaft portions.
