摘要： A toner supply device (100) in which a toner cartridge (200) can smoothly be inserted and removed. The toner supply device (100) includes a toner supply device main body (300) capable of removably setting the toner cartridge (200) to a setting position. The toner supply device main body (300) includes a guide tray (310) for guiding the toner cartridge (200) along an insertion in direction when the toner cartridge (200) is inserted to and pulled out from the setting position. Thus, the toner cartridge (200) can smoothly be inserted and removed. The guide tray (310) can assume a guide posture for guiding the insertion and removal of the toner cartridge (200), and a retreat posture where the guide tray (310) is being retreated to a retreat position.
