Abstract
A toner container includes a shutter to open and close an opening into which the nozzle is inserted, a guide rod provided together with the shutter, and a compression spring that urges the shutter in the closing direction. Further, the toner container includes a holder including a holding portion including at least two portions to support the guide rod movably in an opening and closing direction, a fitting portion having the opening, to fit into a container body, and a bridge portion to connect the holding portion and the fitting portion. A circumferential area around the guide rod and the compression spring that faces the bridge portion is smaller than a circumferential area around the guide rod and the compression spring that does not face the bridge portion. the shutter and the guide rod (or the nozzle) moves smoothly in the opening and closing direction.
