A toner case includes a case main body and a cover. The case main body stores a toner. The cover covers a face of the case main body at one end side in a longitudinal direction of the case main body. An inside projection or an inside recess is provided on an inner face of the cover at a position to be touchable from an outside. A number of the inside projection or the inside recess is determined based on a color of the toner stored in the case main body.

An image forming apparatus includes a cartridge storage portion that is installed in an image forming apparatus main body, and a toner cartridge that is configured so as to be able to be inserted into and removed from the cartridge storage portion. The cartridge storage portion has a storage opening that receives the toner cartridge, and has a gap between an end part of the toner cartridge and the storage opening, through which the end part of the toner cartridge is not able to be held, when the toner cartridge is stored in the cartridge storage portion.

A toner container according to one example embodiment includes a latch catch projecting upward on a top of a body of the toner container. The latch catch is spaced from a second longitudinal end of the body and positioned closer to the second longitudinal end of the body than to a first longitudinal end of the body. The latch catch includes a first contact surface that faces toward the second longitudinal end of the body for contacting a first corresponding surface of a latch in an image forming device to restrain the toner container along a longitudinal dimension of the toner container in a direction from the first longitudinal end of the body toward the second longitudinal end of the body when the toner container is in an installed position in the image forming device.

A toner container for use in an image forming device according to one example embodiment includes a body having a reservoir for holding toner. The toner container includes an electrical connector having an electrical contact for contacting a corresponding electrical contact in the image forming device when the toner container is installed in the image forming device. The electrical connector is positioned in one of a plurality of predetermined positions relative to the body corresponding to at least one of a toner color and a toner type of the toner container for limiting installation of the toner container to one of a plurality of toner container receptacles in the image forming device corresponding to at least one of the toner color and the toner type of the toner container.

An example connection structure includes a connector and a connector support body. The connector is to engage with a coupler of a toner cartridge at a driving position when the toner cartridge is located at an operable position. The connector support body is rotatable about a rotation axis. The connector is also to support the connector to allow the connector to be inclined toward one side or another side with respect to the rotation axis while moving along the rotation axis with respect to the driving position.

An assembly for an image forming device according to one example embodiment includes a toner container removably installable in the image forming device and a latch movable between a latching position restraining the toner container along a longitudinal dimension of the toner container and an unlatching position freeing the toner container to move along the longitudinal dimension of the toner container. A latch actuator has a user engagement surface that is movable along the longitudinal dimension of the toner container between a home position and an actuating position. Pushing the user engagement surface moves the latch actuator from the home position toward the actuating position causing the latch actuator to move the latch from the latching position to the unlatching position to free the toner container for removal from the image forming device.

A toner container is detachably attachable to a developing device. The developing device includes an inlet to be poured with a toner, an inlet shutter to move between a closed position, at which the inlet is closed, and an open position, at which the inlet is open, a biasing mechanism to bias the inlet shutter toward the closed position, an engaged structure provided in the inlet shutter, an engaging structure to engage with the engaged structure and to retain the inlet shutter at the open position against a biasing force of the biasing mechanism, and an engagement releasing structure provided in the inlet shutter and to release an engaging state between the engaged structure and the engaging structure. The toner container includes a contacting surface to contact with the engagement releasing structure and to make the engagement releasing structure release the engaging state.

An image forming apparatus includes a cartridge storage portion that is installed in an image forming apparatus main body, and a toner cartridge that is configured so as to be able to be inserted into and removed from the cartridge storage portion. The cartridge storage portion has a storage opening that receives the toner cartridge, and has a gap between an end part of the toner cartridge and the storage opening, through which the end part of the toner cartridge is not able to be held, when the toner cartridge is stored in the cartridge storage portion.

A toner container according to one example embodiment includes a pivotable handle. The handle includes a front segment extending along a front of a body of the toner container when the handle is in a first position for contacting a corresponding pry surface in an image forming device when the handle moves from the first position to a second position. The handle includes a rear segment extending along a rear of the body when the handle is in the first position permitting a user to actuate the rear segment to move the handle from the first position to the second position. The handle includes a first side segment extending along the first side of the body and a second side segment extending along the second side of the body. The first and second side segments connect the front segment and the rear segment.
