Abstract: An attached portion of an image forming apparatus includes a rotating member of which at least a part is exposed outside the image forming apparatus when the developer container is attached, and a rotation restricting mechanism that is movable between a restricting position to restrict rotation of the rotating member and an allowable position to allow rotation of the rotating member, and includes a restricting member that is at the restricting position when the developer container is not attached. The developer container is attached to the attached portion so that the discharging portion engaging portion and the shutter engaging portions are engaged with the frame engaged portions and the rotating member engaged portions respectively when the container shutter is in the close state, and the restricting member moves from the restricting position to the allowable position when the developer container is attached to the attached portion.

Abstract: A toner container includes a bag body, a coupling member, and a discharge member. The bag body includes a side portion and has, formed in the bag body, storage space configured to store toner and having flexibility. The coupling member is coupled with an opening of the bag body. The discharge member discharges the toner stored in the storage space. The side portion extends in a first direction from the opening to a bottom portion opposite the opening. Two-dimensional code is provided on an outer surface opposite an inner surface of the side portion that forms the storage space for toner. The two-dimensional code is located closer to the bottom portion than to the opening in the first direction.

Abstract: An image forming system includes a toner container and an image forming apparatus to which the toner container is detachably mountable. The image forming apparatus includes a mounting portion to which the toner container is detachably mountable. The toner container includes an accommodating portion configured to accommodate toner, a discharge portion provided with an opening for discharging the toner in the accommodating portion to outside of the toner container, a rotatable member rotatable, relative to the discharge portion, about a rotational axis in a first rotational direction and a second rotational direction that is opposite to the first rotational direction, and a projection provided below the opening of the discharge portion, the projection having inner peripheral surface such that, when the toner container is oriented in a predetermined direction in which the rotational axis extends in a direction of gravity and at least a part of the discharge portion is below the accommodating portion, the inner peripheral surface faces inward in a radial direction of an imaginary circle centered on the rotational axis.

Abstract: In an image forming apparatus, a driving mechanism rotates a bottle attached to a bottle attaching portion by engaging with a first end of the bottle. A cover member, positioned to face a second end of the bottle, is supported to be able to open and close an opening from which the bottle is inserted. An elastic member applies upwards elastic force to the bottle attaching portion. A level sensor detects a position of the bottle attaching portion in an up-down direction. A signal processing device executes a full-state notifying process when a detection signal of the level sensor during operation of the driving mechanism fails to satisfy an abnormality condition, and the position indicated by the detection signal is lower than a predetermined reference position. The abnormality condition includes either or both of an amplitude condition and a cycle condition for a rotation cycle of the bottle.
