A toner guide member includes a toner discharge port that is located above and faces a toner introduction port of a waste toner container, and the toner guide member forms, in its inside, a passage of waste toner from an end portion of a drum cleaning device to a toner discharge port. A first paddle conveyance member including a plurality of first blade portions rotates in a first rotation direction in the toner guide member. A second paddle conveyance member including a plurality of second blade portions rotates in a second rotation direction that is opposite to the first rotation direction, at a position lower than the first paddle conveyance member. A pivotal trajectory of the plurality of first blade portions partially overlaps with a pivotal trajectory of the plurality of second blade portions.

A waste toner transport unit includes a waste toner transport path through which waste toner removed from a circumferential surface of an image carrier is transported, a transport member that transports the waste toner along the waste toner transport path, and a movement restrictor that restricts the movement of the waste toner in a process of waste toner transportation. The waste toner transport path includes an area in which an inner bottom surface is inclined and the area constitutes the movement restrictor. The transport member is disposed such that a rotation shaft extends along the inclined inner bottom surface.

A photosensitive drum is rotatably supported in a main body. A developing cartridge is detachably mountable on the main body in a state where the photosensitive drum is supported in the main body. The developing cartridge includes a developing device and a frame. The developing device includes a developing roller disposed in confrontation with the photosensitive drum to supply developer to the photosensitive drum when the developing cartridge is mounted in the main body, and a developer-accommodating portion configured to accommodate developer. The frame includes a waste-developer-accommodating portion configured to accommodate waste developer and supports the developing device that is movable relative to the frame. The frame is disposed on an opposite side of the developing roller from the photosensitive drum. An urging member is disposed between the frame and the developing device to urge the developing roller toward the photosensitive drum.

A toner container includes a first rotation member rotatably provided in a container main body, a stirring member rotatably provided in such a way as to be parallel to the first rotation member, a lid member closing an opening portion of the container main body, a first bearing portion provided on an inner surface of the lid member and rotatably supporting a first end portion of a first rotation shaft of the first rotation member, a stirring bearing portion provided on the inner surface of the lid member and rotatably supporting a lid-side end portion of a stirring rotation shaft of the stirring member, a storage concave portion formed on the lid member and recessed from an outer surface of the lid member inward, and a transmission mechanism provided in the storage concave portion to transmit a rotation of the first rotation shaft to the stirring rotation shaft.

A toner container is elongated. A first rotating member is rotatably provided in a first toner storage portion and extends in a depth direction of a container main body. A first drive input portion is provided at an end of a first rotation shaft included in the first rotating member and configured to receive a driving force. A second rotating member rotatably provided in a second toner storage portion and extends in the depth direction. A second drive input portion is provided at an end of a second rotation shaft included in the second rotating member and configured to receive a driving force. The container main body includes a plate-like coupling member coupling a first housing of the first toner storage portion with a second housing of the second toner storage portion.

A toner container includes an elongated container main body, a first toner storage portion provided in one side of the container main body in its longitudinal direction, a first rotation member rotatably provided in the first toner storage portion, a second toner storage portion provided in the other side of the container main body in the longitudinal direction, and a second rotation member rotatably provided in the second toner storage portion. The container main body includes a flat plate-like lid member closing opening portions of a first housing of the first toner storage portion and a second housing of the second toner storage portion. First and second bearing portions rotatably supporting a first end portion of a first rotation shaft of the first rotation member and a second end portion of a second rotation shaft of the second rotation member are provided on an inner surface of the lid member.

An image forming apparatus includes a chassis having an opening, a cover, photosensitive members, an intermediate transfer belt, a primary-transfer member, a secondary-transfer roller, a cleaner device, an external-sheet inlet, a waste toner container, a connector, and a conveying roller, which is arranged within the feeding path to feed the recording sheet inserted through the external-sheet inlet in the feeding path. The conveying roller is mounted on the waste toner container and removable from the chassis along with the waste toner container.

A processing apparatus including an apparatus housing, powder processing unit for processing powder, a powder recovery unit for recovering discharged powder, a powder discharge unit for transporting and discharging the powder to a discharge portion to be recovered, and a powder receiver. The powder recovery unit is attached to the apparatus housing and the power receiver is positioned below the powder recovery unit on the same side of the apparatus housing that the powder recovery unit is attached to the apparatus housing. When the powder recovery unit is detached from the apparatus housing, the powder receiving unit receives powder discharge falling from the discharge portion.
