Abstract
A developer supply container for use with an image forming apparatus includes a shell having an air passage and a discharge nozzle, a developer storage pouch storing developer contained inside the shell, and a discharging nozzle for discharging the developer accommodated in the developer storage pouch to outside of the developer supply container. In addition, an air passage allows air to communicate between inside and outside of the shell, and a seal attached to the shell seals the air passage to maintain a pressure inside the shell in a negative pressure state which is lower than a pressure outside the shell. The developer storage pouch is deformed to discharge the developer by peeling the seal off the shell to permit air to enter the shell through the air passage.
