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.
