Abstract
A toner container for an image forming apparatus is made up of a deformable, hermetic bag packed with toner and a box accommodating the bag. A mouth member is affixed to the bag. A powder pump sucks the toner out of the bag and replenishes it to a developing device included in the image forming apparatus. After the toner container has run out of toner, it can be transported or otherwise dealt with at an extremely low cost. In addition, the toner preserves its property despite the delivery to the developing device.
