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.

Powder container and image forming apparatus

Powder container including a container portion to be engaged with a powder replenishing device

A powder container includes a rotatable powder chamber for containing powder used for forming images, having an opening on a first side in an axial direction of the powder container, a conveyor to transport powder contained in the powder chamber to the first side from a second side in the axial direction, a protrusion radially projecting from an outer circumferential surface of the powder chamber, disposed in a circumferential area of the powder chamber, and a facing member disposed facing the outer circumferential surface of the powder chamber. The protrusion contacts the facing member as the powder chamber rotates.

Powder container and image forming apparatus incorporating same

A cap is configured to be attached to a developer container that discharges developer contained in the container body out of the container body through a discharge port defined in a portion of the container body. The cap includes a first attaching member and a second attaching member that are detachably assembled into one piece. When the first attaching member or the second attaching member receives a rotary force, the first attaching member and the second attaching member are separated from each other, and only the first attaching member is released from the container body.
