Abstract: A powder container includes a nozzle receiving opening, a container body, a nozzle receiver including the nozzle receiving opening; a gear, and two scoops. Further, there is a shutter to open and close the nozzle receiving opening, a spring to bias the shutter, two protrusions which protrude away from the nozzle receiving opening. The scoops extend in the longitudinal direction along a first length, the protrusions extend in the longitudinal direction along a second length, and a position of the first length and a position of the second length at least partly overlap along the longitudinal direction. The powder dropped from the higher position enters the region by passing between the protrusions when the scoops are rotated about the rotational axis, and the protrusions are rotated, due to the rotation of the gear, around the region when the scoops are rotated about the rotational axis.

Abstract: A powder container including a nozzle receiving opening at one side of the powder container in a longitudinal direction of the powder container, a scoop, at the one side, to scoop up the powder, when the scoop is rotated about a rotational axis, and a holder, at the one side, which is rotatable around the rotational axis relative to the scoop. The holder includes an electrical terminal, facing the longitudinal direction, and the holder and the electrical terminal not intersecting the rotational axis. The electrical terminal is oblique to the rotational axis relative to a vertical direction when the powder container is in a mounted orientation.

The control device includes a first acquisition unit configured to acquire a first image captured by the image capturing device, a second acquisition unit configured to acquire a second image used to lead a mental state of the wearer to a target mental state, and a composition unit configured to composite the first image and the second image, thereby generating a third image to be displayed on the display device.

Abstract: 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.

Abstract: An image forming apparatus includes an apparatus body and a detachable unit to be attached to the apparatus body in an attachment direction and detached from the apparatus body in a detachment direction. The detachable unit includes a rotary body and a unit drive gear. The apparatus body includes an apparatus-body drive gear to engage with the unit drive gear of the detachable unit attached in the apparatus body, at an engageable position on a downstream side of the apparatus-body drive gear in the attachment direction. One or each of the unit drive gear and the apparatus-body drive gear moves to a retracted position at which the one or each of the unit drive gear and the apparatus-body drive gear does not engage with the other of the unit drive gear and the apparatus-body drive gear and does not interfere with attachment and detachment operations of the detachable unit.

Abstract: 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.
