The invention phenomenon even if there is, if the the tasks that removably mounted (着 脫) to the mounting portion of the image forming apparatus main body container, for example if the position of the mounting portion increased and that the heavy weight of the containers and the phenomenon will be a challenge to provide an image forming apparatus in which charge can be performed easily is reduced. And a developer an image forming apparatus main body 10 includes a container mounting portion 15, which is a developer container 50 for containing a detachably attached to, housed inside the same time that the developer container is mounted, the container mounting portion (格納) at least a portion of the position and the image-forming apparatus having a support member 70, the container mounting member 60 attached to the support so as to move between a withdrawal position outside of the body, vessel mounting member 60 from the container mounting portion is, in the take-off position from the container mounting portion (50), displaced through a rotary shaft 61 provided in the support member 70 to the position of the lower below the height of the gravity in the direction of such a take-off position. A developer container, an image forming apparatus, the container mounting portion, the support member, the vessel mounting member
