An image forming apparatus includes a first seal, on which a first discrimination mark is displayed, provided at a position corresponding to a first mounting portion for mounting a first collecting container for collecting residual toner, and a second seal, on which a second discrimination mark is displayed, provided at a position corresponding to a second mounting portion for mounting a second collecting container for collecting residual toner. A notifying device notifies, in a case that one of the first collecting container and the second collecting container becomes full, information prompting exchange of the collecting container which becomes full and identifying the collecting container to be exchanged by indicating the first discrimination mark or the second discrimination mark.

Image forming apparatus

There are provided a developer accommodating portion for accommodating the developer, a discharge portion formed with a discharge opening for discharging the developer accommodated in the developer accommodating portion, and an engaging portion. The engaging portionis engaged with an engaged portionwith a mounting operation of a developer supply containerto displace a developer receiving portionin an upward direction U so that the receiving opening communicates with the discharge opening. The engaging portionhas a holding portionwhich is provided rotatably about a rotation shaftand is provided with holding portionto be engaged with the engaged portionto hold the engaged portion. With the mounting operation, the engaging portionrotates about the rotation shaftso that the engaged portionheld by the holding portionmoves upward U.

Developer supply container and developer supplying system

A developer supply container includes a developer accommodating portion accommodating developer, and a developer discharging portion in fluid communication with the developer accommodating portion. The developer accommodating portion is rotatable about a rotational axis and relative to the developer discharging portion, with the developer discharging portion being provided with a developer discharge opening at a bottommost side of the developer discharging portion and configured to permit discharging the developer to outside of the developer supply container. A lifter is linearly liftable relative to the developer discharging portion in a direction perpendicular to a horizontal plane that includes the rotational axis when the developer supply container is oriented with the developer discharge opening positioned at a bottom side of the developer discharging portion.

With a mounting operation of a supply container, a supported portionof a developer receiving portionis supported by a receipt supporting portionof a lifting portion. With further mounting operation, a shutter sliding portionof the lifting portionslides on a shutter inclined portionof a shutter. The developer receiving portionis displaced so as to bring a receiving opening into communication with a discharge opening by operating, using the shutter, the lifting portionsupporting the supported portionof the developer receiving portion. By this, a load required for movement of the developer receiving portionis reduced to achieve smooth mounting of the supply container.
