A toner container includes a first chamber for accommodating toner and provided with an outlet port through which the toner is discharged outside of the toner container, a second chamber provided with an inlet port and for accommodating toner to be received from an outside of the toner container through the inlet port, a stirring member for stirring the toner accommodated in the first chamber and to rotate about a rotational axis, and an air supply unit configured to supply air for discharging the toner accommodated in the first chamber to an outside of the toner container through the outlet port. The air supply unit, the first chamber, and the second chamber are aligned in this order in a direction of the rotational axis.

Toner container

A toner cartridge includes a toner accommodating unit including first and second accommodating portions and includes a light transmitting portion having an incident surface and an emergent surface. The toner accommodating unit includes first and second end portions with respect to a first direction and includes third and fourth end portions with respect to a second direction crossing the first direction. The first accommodating portion is provided with a discharge opening, and the second accommodating portion is provided with a receiving opening. The discharge opening and the receiving opening are positioned closer to the third end portion than to the fourth end portion in the second direction. The incident surface and the emergent surface are provided in positions closer to the fourth end portion than to the third end portion in the second direction and are exposed to an outside of the cartridge.

Side cover for process cartridge for image forming apparatus

A process cartridge of an image forming apparatus includes a seal member to seal a first gap between an end portion of a developer bearing member and a frame, and a sealing portion that seals a second gap between the frame and an end portion of the seal member. The frame includes an injection inlet through which elastomer has been injected into the second gap for forming the sealing portion, a storage portion that is a space surrounded by a second surface of the frame and a wall protruding from the second surface and in which elastomer spilling out of the second gap is stored, and a protruding portion that protrudes, from the second surface of the frame, further than the wall of the storage portion. The protruding portion contacts a conveyed recording medium when the process cartridge is mounted in an apparatus main body of the image forming apparatus.

Developing apparatus having a sealed developer bearing member, process cartridge, and image forming apparatus

A first supporting member includes a first engaging portion and a second engaging portion that respectively engage with a first engaged portion and a second engaged portion that are provided in a second supporting member. The first engaging portion and the second engaging portion are configured to apply force in directions opposite to the directions in which the first engaged portion and the second engaged portion move when an opening opens.

Frame, cartridge, image forming apparatus, and method for manufacturing frame

A conveying device in which a circle formed of a trajectory drawn by a distal end of an engaging portion and an axial line of a driven shaft intersect each other when viewing in an axial direction of a drive shaft, and a slope of the driven shaft with respect to a horizontal direction is an angle not larger than an angle of repose of a developer when viewing in the axial direction of the drive shaft is provided.

Conveying device having a first conveyance member that transmits driving force to a second conveyance member

A cartridge includes a frame; a rotatable member for carrying a developer; a blade member contacting the rotatable member; a first seal member provided extended in a rotational axis direction of the rotatable member between the blade member and the frame so as to contact the blade member and the frame; a second seal member provided extended in a direction crossing the rotational axis direction of the rotatable member between the rotatable member and the frame so as to have a first surface contacting the first seal member; and a second surface provided on the frame and extended in a direction crossing the rotational axis direction of the rotatable member so as to contact the first seal member. The first seal member includes a portion sandwiched between the first surface and the second surface with respect to the rotational axis direction.
