Abstract
A toner container that is removably attached to a toner feed device for feeding toner to a developing unit provided for an image forming apparatus, includes: a container body filled with toner; and a supporting structure, which supports the container body in a rotatable manner by enclosing the outer peripheral surface along the rotational direction of the container body so as to include the area where a toner feed recess is formed, and has a toner feed aperture for feeding the toner discharged from a toner discharge aperture of the container body into the toner feed recess, to the outside. The supporting structure includes a shutter opening and closing mechanism having a shutter element that is movable along a fixed direction to open and close the toner feed aperture. This shutter opening and closing mechanism in the supporting structure is formed with an anti-slide portion for restraining the movement of the shutter element before the toner container is mounted to the toner feed device.
