An image forming apparatus includes an image forming portion, an intermediary transfer belt, a first mounting portion for mounting a first collecting container, a second mounting portion for mounting a second collecting container, and a feeding device including a first discharging portion and a second discharging portion. The first mounting portion and the second mounting portion are provided below the intermediary transfer belt and are disposed side by side in a widthwise direction perpendicular to a rotational axis direction of the image bearing member. As viewed in the vertical direction, each of the first mounting portion and the second mounting portion is provided at a position where at least a part of the mounting portion overlaps with the intermediary transfer belt.

An image-forming apparatus includes an apparatus body and a process cartridge attachable to and detachable from the apparatus body. The apparatus body includes a sheet-feed roller and a body wall. The process cartridge includes: a photosensitive drum; a drum frame; a developing roller; a cleaner; a conveying pipe and a waste-toner container for storing waste toner removed from the photosensitive drum by the cleaner and conveyed by the conveying pipe. The waste-toner container is detachably mountable on the drum frame. The waste-toner container mounted on the drum frame is positioned opposite to the photosensitive drum with respect to the developing roller. The body wall of the apparatus body and a container wall of the waste-toner container constitute a part of a sheet-conveying guide for guiding conveyance of a sheet from the sheet-feed roller toward the photosensitive drum when the process cartridge is attached to the apparatus body.

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 toner container including non-volatile memory is mounted to a first mounting section, and a toner container already used is mounted as a waste toner bottle to a second mounting section. Every time a supplied amount of toner is calculated, a writing section writes an integrated value of the supplied amount as a current value and a maximum value in the non-volatile memory. Every time the generated amount of waste toner is calculated, an updating section updates the current value stored in the non-volatile memory by subtracting the generated amount from the current value. A detecting section detects fullness of the waste toner bottle when the current value stored in the non-volatile memory of the toner container mounted as the waste toner bottle to the second mounting section becomes no greater than a value obtained by subtracting an initial remaining space of the toner container from 0.

A drum cartridge includes: a photosensitive drum rotatable about a drum axis extending in an axis direction; a drum cleaner including a cleaning member cleaning a circumferential surface of the photosensitive drum, and a cleaning housing accommodating transfer residual toner removed from the circumferential surface of the photosensitive drum by the cleaning member; a first drum side plate supporting a first end portion of the photosensitive drum; a second drum side plate located distant from the first drum side plate in the axis direction and supporting a second end portion of the photosensitive drum; a pipe located between the first drum side plate and the second drum side plate in the axis direction and extending in the axis direction; and a conveyor device conveying the transfer residual toner from the cleaning housing to the pipe.

A developer storage device that stores developer includes a frame having an internal space and an inlet, a partition portion for partitioning the internal space into first and second chambers, the partition portion including a communication port through which the first and second chamber communicate, a conveyance portion arranged in the internal space and configured to convey the developer, and a detection unit detecting an amount of the developer stored in the first chamber. When the amount of the developer in the first chamber is less than a predetermined value, the developer is conveyed to a far side portion of the first chamber by the conveyance portion. When the detection unit detects that the amount of the developer in the first chamber reaches the predetermined value or more, the conveyance portion conveys the developer to the second chamber.

A recovery container includes a container body, a discharge port, an opening/closing part, a guide part, and an inclination suppressing part. The container body with a recovery path is removably attached to an attachment target. The powder transported through the recovery path is discharged to outside through the discharge port. The opening/closing part closes the discharge port. In an attached state in which the container body is attached to the attachment target, the opening/closing part is push-opened by a periphery of a recovery port provided in the attachment target. The guide part extends in the attachment direction of the container body to guide movement of the opening/closing part. The inclination suppressing part comes into contact with a portion of the attachment target before the periphery of the recovery port comes into contact with the opening/closing part to suppress inclination of the container body.

A waste toner collecting device includes a waste toner container, a detector, and an auger. The waster toner container is to collect waste toner. The detector is to detect an amount of waste toner collected and accumulated in the waste toner container. The auger is to disperse the waste toner in the waste toner container. The auger includes a first blade to transport the waste toner in a first direction toward the detector in the waste toner container, and a second blade to transport the waste toner in a second direction opposite to the first direction in the waste toner container. The second blade includes a first blade section having a waste toner transport rate greater than a waste toner transport rate of the first blade.

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 process cartridge having a drum cartridge and a toner cartridge is provided. The drum cartridge includes a photosensitive drum, a cleaner, a conveyer tube, a developing roller, and a developing device. The toner cartridge is attachable to the drum cartridge and is located on a side of the developing roller opposite to the photosensitive drum in an attaching direction. The toner cartridge includes a waste toner container to store the toner conveyed through the conveyer tube and a toner container to store the toner to be supplied to the photosensitive drum. The toner container communicates with a developing chamber in the developing device and is located at least partly between the waste toner container and the developing chamber. The conveyer tube extends in the attaching direction and is arranged to overlap the photosensitive drum, the toner container, and the waste toner container in a view along an axial direction.
