Abstract
A toner supply device includes a pressing portion that presses a toner cartridge such that the toner cartridge is detached from a device body. The toner cartridge has an engaging portion. The device body has a guiding portion. The guiding portion has an upper guide groove that guides the engaging portion in an attachment operation of attaching the toner cartridge to the device body, and a lock portion provided at a position deviated from the upper guide groove in an innermost portion of the guiding portion. When the engaging portion moving in the upper guide groove along with the attachment operation reaches the innermost portion, the engaging portion is engaged with the lock portion by the pressing portion pressing back the toner cartridge, allowing the toner cartridge to be attached to the device body so as not to be detached therefrom.
