A toner container includes a container body, an opening, a cover, a toner discharge port, a shutter, a cylindrical structure, protrusions, and an identifier. The shutter is attached to the cover and includes a main shutter covering the toner discharge port. The main shutter moves between a closed position to close the toner discharge port and an open position to open the toner discharge port. The protrusions are on both sides of the cover and protrude in a direction orthogonal to a toner container mounting direction. The identifier is on the cover to indicate a toner color. The cylindrical structure's leading end is downstream of leading ends of the protrusions in the mounting direction. The main shutter's leading end is downstream of the protrusions' leading ends in the mounting direction when the main shutter is in the closed position. The protrusions are downstream of the identifier in the mounting direction.

Information storage system including a plurality of terminals

Provided is a powder container having a new structure capable of stable discharge and transport of a powder contained in a container by enabling the powder to be reliably discharged to the outside of the package while preventing the powder from spilling and flying out of the container. The powder container has a container body () for transporting powder contained therein from a first end side () to a second end side () thereof by self-rotating; a nozzle receiver () having a nozzle receiving hole (insertion section) () arranged inside the second end side of the container body and configured to allow a transport nozzle () having a powder receiving inlet () to be inserted therein, and a supply portarranged in at least a part of the nozzle receiver () and configured to supply the powder in the container body () to the powder receiving inlet (): and a shutter () supported by the nozzle receiverand configured to open and close the nozzle receiving hole (insertion section)by sliding in response to insertion of the transport nozzleinto the nozzle receiver ().

Powder container, powder supply device and image forming apparatus

The powder container includes a container body containing a powder for image formation, the powder being to be supplied to a powder replenishing device; a conveyor configured to convey the powder from one end in a longitudinal direction to the other end at which a cylindrical container opening is formed, the conveyor being provided inside the container body; a gear configured to rotate the conveyor with an external driving force; a container cover configured to cover the gear, the container cover having a gear exposing hole for partially exposing a gear tooth; and a nozzle receiver configured to guide the conveying nozzle inside of the container body, the nozzle receiver being provided on the container opening. The container cover includes a container engaged portion provided outer than the tooth of the gear in a radial direction.
