A tie attachment assembly, including a first layer including a first surface and a second surface, the first surface including an adhesive, a fold line, and a second layer, including a third surface, a fourth surface connected to the first surface, a first cutout arranged on a first side of the fold line, and a second cutout arranged on a second side of the fold line, opposite the first side.

A toner container for use with an image forming apparatus is provided with a toner accommodating portion in which toner is accommodated; a base portion including a receiving opening for receiving the toner accommodated in the toner accommodating portion, a discharge opening for permitting discharge of the toner, received through the receiving opening, to an outside of the toner container, and a passage which is a passage extending from the receiving opening to the discharge opening and which is for permitting passing of the toner; and a shutter constituted so as to be rotatable about a rotational axis relative to the base between an open position where the discharge opening is exposed to the outside and a closed position where the shutter covers the discharge opening, wherein the passage extends in a direction in which the passage is inclined relative to the rotational axis so that the receiving opening is in a position where the receiving opening crosses the rotational axis and so that the discharge opening is in a position where the discharge opening does not cross the rotational axis.

A toner cartridge includes a pump portion that is variable in volume, a feeding path portion including a connection opening connected to the pump portion at a first end and including a discharge opening at a second end, and a toner accommodating portion connected to an intermediate portion between the first end of the feeding path portion and the second end of the feeding path portion. A volume change amount of the pump portion is greater than a total volume from the connection opening to the discharge opening.

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.

A toner container includes a toner accommodating body and a nozzle including an opening configured to form a part of a discharge passageway through which toner may be discharged to outside of the toner container. A shutter is configured to open and close the opening of the nozzle, with the shutter being rotatable about a rotational axis between a first position in which the shutter closes the opening of the nozzle and a second position in which an opening of the shutter aligns with the opening of the nozzle to form the discharge passageway. A projection is positioned at an end portion of the toner container, with the projection including a first surface, a second surface, and a third surface. When the toner container is oriented such that the toner accommodating body is above the nozzle, the nozzle is above the projection, and the projection is at a bottommost side of the toner container, (i) the opening of the nozzle is positioned such that toner may be discharged from a lateral side of the toner container that is above the bottommost side, (ii) the first surface faces downward, (iii) the second surface faces downward, and (iv) the third surface faces upward.

An image forming apparatus includes: a detection unit configured to detect an amount of developer stored in a developing container and to output remaining amount information; and a control unit configured to perform control, during a replenishment of the developer to the developing container using a replenishment container, to cause a display unit to display a message related to the replenishment. When the replenishment is instructed, the control unit is further configured to perform a first control during the replenishment in a case where the remaining amount information indicates a first remaining amount, and configured to perform a second control different from the first control during the replenishment in a case where the remaining amount information indicates a second remaining amount greater than the first remaining amount.

A toner container for use with an image forming apparatus is provided with a toner accommodating portion in which toner is accommodated; a base portion including a receiving opening for receiving the toner accommodated in the toner accommodating portion, a discharge opening for permitting discharge of the toner, received through the receiving opening, to an outside of the toner container, and a passage which is a passage extending from the receiving opening to the discharge opening and which is for permitting passing of the toner; and a shutter constituted so as to be rotatable about a rotational axis relative to the base between an open position where the discharge opening is exposed to the outside and a closed position where the shutter covers the discharge opening, wherein the passage extends in a direction in which the passage is inclined relative to the rotational axis so that the receiving opening is in a position where the receiving opening crosses the rotational axis and so that the discharge opening is in a position where the discharge opening does not cross the rotational axis.

A toner cartridge includes a container having an opening, a flexible bag in which toner is received, a sealing portion configured to seal the flexible bag, and an extension extending from an edge of the sealing portion, the flexible bag being accommodated in the container so that the sealing portion faces the opening, a rotatable member rotatably provided on the container, a movable member connected to the extension and being movable from a first position close to the opening to a second position far from the opening in a longitudinal direction of the container, a rope having a first end portion connected to the rotatable member and a second end portion connected to the movable member, and a bias member configured to elastically bias the rotatable member to rotate in a direction in which the rope is switched from an unwound state to a wound state.

Provided is an image forming unit contained in a flexible bag and held to allow a cushion member to absorb shock. The image forming unit includes: an image carrier on which an electrostatic latent image is formed; a developing device including a developing unit that is configured to develop the electrostatic latent image by turning around a turning center and coming into contact with the image carrier; and a developer accommodating portion that accommodates a developer for use in the developing device. The image forming unit also includes a restricting portion that is provided on an outermost portion of the developing device to come into contact with the cushion material so that rotation of the developing device is restricted.
