Abstract

A developing agent replenishing device includes: a developing agent storing container having a spiral protrusion in an interior thereof, including a container main body for storing therein a developing agent and a movable cover for opening or closing a developing agent discharging opening provided on one end of the container main body; a container mounting section to which the storing container is mounted, wherein the developing agent stored in the storing container is discharged by rotating the storing container; a developing agent reserving section for reserving therein the developing agent discharged from the storing container; a cover engagement portion for engaging with the movable cover when the storing container is mounted to the container mounting section; and a holding and moving device for holding a part of the storing container and for moving the storing container when the storing container is mounted to the container mounting section. The movable cover and the storing container main body are relatively moved by moving the storing container by the holding and moving device, thereby the discharging opening is opened, and consequently communicates with the developing agent reserving section so that the developing agent in the storing container can be discharged.
