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: In some examples, an apparatus can include a mating interface coupled to a dispense interface to interact with a print particle dispense nozzle, a locking mechanism coupled to the dispense interface to prevent the print particle dispense nozzle from depositing a print particle to the dispense interface, and an authentication mechanism coupled to the locking mechanism to: authenticate the print particle dispense nozzle, and unlock the locking mechanism when the print particle dispense nozzle is authenticated to allow the print particle dispense nozzle to deposit the print particle to the dispense interface.

Abstract: A printer includes a main body including a communicating portion, a development cartridge attachable to and detachable from the main body, the development cartridge to supply toner contained in a toner container to an electrostatic latent image formed on a photoconductor, to form a visible toner image, and a toner refilling portion connected to the toner container. The toner refilling portion includes a mounting portion into which a toner cartridge insertable from outside the main body through the communicating portion to be mountable, a toner inlet portion provided in the mounting portion to receive toner from the toner cartridge when the toner cartridge is mounted to the mounting portion, and an inlet shutter switchable between a blocking position where the toner inlet portion is blocked from receiving toner, and an inlet position where the toner inlet portion is open to receive toner. The printer includes a first latch member switchable between a first position where the inlet shutter is locked from switching between the blocking position and the inlet position and a second position where switching of the inlet shutter is allowed to switch between the blocking position and the inlet position, and a switching unit to switch between the first latch member between the first position and the second position.
