ABSTRACT:
In this developing toner supply device, the main body of a toner cartridge having an unused toner storing room is designed in a longitudinal vessel shape. A projecting portion is projected from the front wall of the cartridge at the casing side to engage with the recess portion of a toner storing portion. A semi-circular support wall is formed at the projecting portion to project toward the unused toner storing room side. A longitudinally-extending cartridge side opening is formed on the support wall. A semi-cylindrical cartridge side rotating member engages with the cartridge side and opens rotatably between the closing position where the cartridge side opening is closed and the opening position where the cartridge side opening is opened. When the toner cartridge is detached from the casing, the cartridge side opening is closed. The flat side surface of the cartridge side rotating member serves as the outer surface of the toner cartridge. Accordingly, toner attachment to the outer surface of the toner cartridge can be avoided as much as possible.
