Abstract: A toner container includes: a bag having an opening; a discharge member having a receiving port aligned with the bag in a first direction and for receiving toner, and a discharge port for discharging the toner; and a shutting member shutting the discharge port. The receiving port is provided on an inner side with respect to the opening in a second direction orthogonal to the first direction. The receiving port is open in the first direction and has an area greater than or equal to 25 mm2. The discharge member has a fixing portion to which the opening is fixed, and a surface between the fixing portion and the receiving port. A filling amount [g] of the toner with respect to a total volume [cm3] up to which the toner in the toner container is allowed to be contained is less than or equal to 0.547 [g/cm3].

Abstract: A toner container is provided with a bag member made of flexible film material and a discharging member connected to the bag member and configured to discharge toner from an accommodating space to an outside. When a length from an opposing surface of the discharging member to an end portion in an opposite side of the opposing surface of the bag member in a first direction is defined as Xmax, and in a case in which a position X (0≤X≤Xmax) using the opposing surface as a reference in the first direction is given, a length of the bag member on a plane perpendicular to the first direction in a second direction is defined as Y and a length of the bag member on the plane in a third direction is defined as Z, in a case in which Z is Z0 in X=0, Xmax>Y≥Z in a range of 0≤X≤Xmax, 0.8×Z0≤Z≤1.2×Z0 in the range of 0≤X≤Xmax, and Y≤2×Z in a range of 0≤X

Abstract: [Problem] To provide a form of a container for use with an image forming apparatus
[Solution] A container for use with an image forming apparatus and for accommodating a content of powder or a liquid, the container includes an accommodating portion configured to accommodate the content; an end portion including a discharging portion which includes a discharge opening for permitting discharge of the content to an outside of the container and a passage configured so that the content passes through the passage toward the discharge opening, and including a shutter configured to be movable relative to the discharging portion between a shielding position where the shutter shields the discharge opening and an open position where the shutter opens the discharge opening; and a cap mounted to the end portion so as to cover at least a part of the end portion and configured to be dismounted from the end portion by being rotated relative to the end portion.

Abstract: A toner container includes a storage portion configured to store toner and a communicating member including a receiving port, a discharge port, and a passage. The passage includes a first inclined surface and a second inclined surface connecting the first inclined surface and the discharge port to each other. When viewed in a third direction perpendicularly intersecting with both of a first direction and a second direction, the first inclined surface is inclined with respect to the second direction such that a more downstream portion of the first inclined surface in the first direction is closer to the discharge port in the second direction, and the second inclined surface is inclined with respect to the second direction such that a more downstream portion of the second inclined surface in the first direction is closer to the discharge port in the second direction.

Abstract: A cartridge to which a toner container is detachably attachable includes a development roller, a storage unit to store toner to be carried by the development roller, an attachment portion, and first, second, and third contact portions on a bottom surface of the cartridge to be brought into contact with a horizontal plane. The cartridge can be oriented in a positioning direction in which the attachment portion is positioned above the storage unit and the cartridge contacts the horizontal plane. When the cartridge in the positioning direction is viewed in a gravity direction, a part of the attachment portion overlaps with a first region. The first region is surrounded by a first virtual line connecting the first and second contact portions, a second virtual line connecting the second and third contact portions, a third virtual line connecting the third and first contact portions, the first, second, and third contact portions.

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.
