The present invention relates to a toner container comprising a container body having a toner discharge part for discharging the toner in the container body to the outside of the container body and arranged at the lower part of the container body in the vertical direction and an opening arranged at the upper part of the container body; an interface unit fixed to the lower central part of the container body, wherein the toner discharge holes of the interface unit are provided with single-layer or multi-layer sealing members having the function of a self-closing valve; a ventilation filter arranged above the opposite side of the sealing members, covering the opening and used for the air to pass through, wherein the toner cannot pass through. When the container body is installed onto the arrangement unit of an image forming device, a fixed nozzle on the arrangement unit of the image forming device can be inserted from right below in the vertical direction. The container body is filled with toner. Due to the adoption of the toner discharge part, the toner in the container body can be supplied to a developing device through a toner inhalation part, a toner transporting pipe, a toner connecting port and a toner pump. The position of the opening is right opposite to the toner discharge part.
