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.

An image forming apparatus includes a main body housing, a photosensitive drum, an exposure device, a developing device, a toner container, a transfer roller, a fixing device, a cleaner and a waste toner container. The main body housing includes a front wall and a rear wall opposite to the front wall in a horizontal direction. The photosensitive drum is located further from the front wall than the photosensitive being from the rear wall. The toner container includes a first front end. The waste toner container including a second front end. A distance between the second front end of the waste toner container and the front wall of the main body housing in the horizontal direction is smaller than a distance between the first front end of the toner container and the front wall of the main body housing in the horizontal direction.

The present disclosure provides a toner cartridge. The toner cartridge includes a toner hopper containing toner, a waste toner bin containing waste toner, and a developing part disposed in the toner hopper. The toner hopper and the waste toner bin are movably connected; and the toner hopper is capable of moving from a first position to a second position relative to the waste toner bin. When the toner hopper is at the first position, the developing part is electrically connected to a printer and capable of receiving a developing voltage signal sent by the printer; and when the toner hopper is at the second position, the developing unit is electrically disconnected from the printer and not capable of receiving the developing voltage signal sent by the printer or not capable of sending an electrical signal to the printer.

A reusable media shell has a frame to hold sheets of media in an interior. A removable cap connects to the frame and its manipulation unveils the media for picking by an imaging device. The cap resides on a terminal end of the frame so the frame covers a majority of the media. A lift plate in the interior forces upward the sheets for picking. Two magnets on the frame magnetically secure the frame to magnets in a base of the imaging device and position the sheets in the base. Upstanding walls, a lid and bottom define the interior of the frame. Inserts attached to the walls allow adjustment to accommodate various sizes of the media.

An image forming apparatus to and from which a replenishment container accommodating toner is detachable and which forms an image on a recording material includes an apparatus body, and a cartridge including an image bearing member, a developer container to accommodate toner, and a developing portion to develop an electrostatic latent image formed on the image bearing member into a toner image by using the toner. A replenishment port allows replenishment of toner from the replenishment container, which is arranged outside of the image forming apparatus, to the developer container therethrough in a state where the replenishment container is attached to the replenishment port, and a controller notifies a user of information related to a toner amount if it is determined that a lifetime of the cartridge will expire before a sum of toner accommodated in the developer container and toner accommodated in the replenishment container is consumed.
