Abstract: There is provided an image forming agent holding container having a container body that is installable into and removable from an image forming device body and in which an ejection hole for use in ejection of image forming agent is formed, an opening/closing part that is shiftably mounted on the container body so as to open and close the ejection hole, and a manipulating part turnably supported by the container body to be used for shifting the opening/closing part relative to the container body, the manipulating part shifting to and from an open position to place the ejection hole in an open state, a sealing position to place the ejection hole in a sealed state, and a fitting position to fit the manipulating part to the container body.

Abstract: A storage container includes a container body formed with a discharge hole and a filling hole, an opening and closing part opening and closing the discharge hole, a lid member sealing the filling hole, and an operating member having a facing portion facing the filling hole and used to operate the opening and closing part. The operating member moves between a first position where the discharge hole is brought into an opened state, a second position where the discharge hole is brought into a closed state, and where the facing portion is arranged at a position which overlaps the container body, and a third position where the discharge hole is brought into a closed state, and where the facing portion is arranged at a position which does not overlap the container body in the direction of gravity in which the sealing part is attached to the container body.

Abstract: An image forming agent storage container includes a container body formed with a discharge hole, a rotary shaft, a stirring part, and a conveying member. The conveying member includes a first end portion, a second end portion and a slit. The first end portion comes into contact with a lower inner face of the container body. The second end portion comes into contact with an inner face of the container body which intersects the lower inner face. The slit is formed between the first end portion and the second end portion. A corner of the conveying member located between the first and second end portions is removed. The slit extends from a portion from which the corner is removed toward an inside of the conveying member.
