A toner conveying device (7a to 7d) includes a toner conveying path (26), a conveying screw (29), and a flicker (31). The conveying screw (29) includes a rotation shaft (29a) and a helical blade (29b) formed on an outer circumferential surface of the rotation shaft (29a). The flicker (31) includes a plurality of first contact pieces (33) that press the conveying screw (29) in a first direction toward a bottom of the toner conveying path (26), and a plurality of second contact pieces (34) that contact the conveying screw (29) from a side opposite to the first contact pieces (33) and press the conveying screw (29) in a second direction opposite to the first direction. A force with which the first contact pieces (33) press the conveying screw (29) is greater than a force with which the second contact pieces (34) press the conveying screw.

An image forming apparatus according to the present disclosure includes a skew correction device and a cleaning device. The skew correction device includes first conveying rollers. The first conveying rollers are rotatable about a predetermined rotation fulcrum. The first conveying rollers are, before a sheet, which is skewed, enters a device body, rotated from an initial position, and, when the sheet enters the device body, rotated back to the initial position while nipping and conveying the sheet. The cleaning device includes a toner conveying member that conveys residual toner on an image-carrying member to a predetermined container. Both the first conveying rollers and the toner conveying member operate by consecutively receiving a rotational driving force from a common electric motor.

An image forming apparatus is provided. The 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.

An image forming apparatus includes a main frame, a plurality of process cartridges, a cartridge-supporting body, a belt, a waste toner cartridge, a contact-separation mechanism, and a collective conveying unit. Each process cartridge includes a photosensitive drum and a drum cleaning unit collecting waste toner on the drum. The cartridge-supporting body is movable between an internal position inside the frame and an external position outside the frame. The belt confronts the process cartridges in the internal position. The waste toner cartridge accommodates the waste toner collected from the drums. The contact-separation mechanism moves the cartridge-supporting body between a contact position where the drums are in contact with the belt and a separated position where the drums are out of contact with the belt. The collective conveying unit aggregates waste toner collected from drums and conveys collectively the aggregated waste toner to the waste toner cartridge.

Provided is a powder recovery device including a recovery container that includes a powder collection chamber therein, recovers used powder transported from a powder processing section that performs a process using powder, and collects the recovered powder in the powder collection chamber, and a transport member that is provided within the recovery container along the longitudinal direction of the recovery container, and evenly transports powder collected in the powder collection chamber, wherein plural recovery ports are provided at positions located higher than a highest location in the recovery container at which powder is collected, and plural air vent ports are at least separately provided at regions with a center of the recovery container in the longitudinal direction of the recovery container interposed therebetween.

A powder collection container that is attachable to and detachable from a mount part of an apparatus and stores powder includes a plurality of walls that form a storage space to store the powder. The plurality of walls include a first wall that faces the mount part of the apparatus and a second wall that does not to face the mount part of the apparatus. A thickness of the first wall is smaller than a thickness of the second wall.

An image forming apparatus includes an image bearing member for bearing a toner image to form a toner image, an intermediary transfer belt onto which the toner image is transferred, a first detachable collecting container to collect residual toner discharged from the image forming portion, and a second detachable collecting container to collect the residual toner discharged from the image forming portion. The first and second collecting containers are provided below a lower surface of the intermediary transfer belt and disposed side by side in a widthwise direction perpendicular to a rotational axis direction of the image bearing member, and at least a part of the first and second collecting containers overlap with the intermediary transfer belt as viewed in the vertical direction. In addition, a length of each of the first and second collecting containers in the widthwise direction is longer than the length in a height direction.
