Abstract
A toner container is detachably attached to a developing device and used for supplying a developing agent held therein to the developing device. The toner container, after completing supply of the toner, is then detachably attached at a position suitable for recovering developing agent remaining on an electrostatic latent image carrier, and allowed to accommodate therein the recovered developing agent. A main body of the toner container accommodates the developing agent. A mouth is formed in the main body, and is adapted to effect supply or recovery of the developing container. A form-changing member effects a change in the form of the main body when the main body is attached in the position for recovery of the remaining developing agent to indicate that the toner container has already been used as a supply container.
