Abstract: An image forming apparatus includes a main body, a development cartridge supplying toner accommodated in a toner accommodating portion to an electrostatic latent image formed on a photoconductor to form a toner image, a toner refilling portion in the development cartridge and on which a toner refill cartridge for refilling toner in the toner accommodating portion is mounted, and a controller controlling operations of the image forming apparatus based on a connection between the development cartridge mounted on the main body and the toner refill cartridge mounted on the toner refilling portion. The toner refilling portion connects the toner refill cartridge to the main body through an interface between the development cartridge and the main body.

Abstract: Examples of a print particle replenishment device for replenishing a host device are described herein. In some examples, the print particle replenishment device includes an output assembly to output print particles, comprising an interfacing portion. In some examples, the print particle replenishment device includes a plurality of contact pads disposed on an outer portion of the output assembly to rotate with the output assembly when opening a channel of the print particle replenishment device.

Abstract: An example operation method of an image forming apparatus includes determining a state of a toner refill operation of injecting toner from a toner reload kit (TRK) into a cartridge in the image forming apparatus, based on completion of injecting toner from the TRK into the cartridge, controlling the TRK to store information indicating a toner refill completion in a memory of the TRK, based on completion of injecting toner from the TRK into the cartridge, updating information of an amount of remaining toner of the cartridge based on an amount of the toner injected into the cartridge from the TRK, and based on the information indicating the toner refill completion being stored in the memory of the TRK, unlocking a locking apparatus in the image forming apparatus so the TRK may be removed from the cartridge.

Abstract: Examples of a host device that includes an input recess are described. In some examples, the input recess includes a rotating port cover offset from a central axis of the input recess. In some examples, the input recess includes a plurality of contacts disposed on an interfacing surface of the input recess to interface with a print particle replenishment device when the rotating port cover is rotated. In some examples, the plurality of contacts interfaces with a control device to authenticate the print particle replenishment device.
