Abstract

PURPOSE:To remarkably increase the number of developable sheets per one piece of cartridge by providing a volume changing means for making a toner storing volume larger than a storing volume being under the loading of the cartridge, on a toner replenishing cartridge body. CONSTITUTION:A bellows member 13b is mounted to a body 13 of a toner replenishing cartridge A so that when said member is contracted, the cartridge becomes a size which can be loaded to a cartridge loading part of a developing device body, and when said member is elongated, a toner storing space is en larged and a storing portion of loss in weight caused by flying-up at the time of storing a toner is covered. When the toner is stored from a toner storing port 17, the toner flies up, and even if it is executed repeatedly two times or three times, 70-80% of the storing volume is a limit, therefore, the capacity is set so as to become 100X1/0.7=143%. In such a way, the storing quantity of the toner is increased substantially, and the number of developable sheets per one piece of cartridge can be increased.
