  • Patent number: 10915041
    Abstract: A powder-container attachment device includes a powder container that accommodates powder, and a device body. The device body includes an attachment portion to and from which the powder container is attached and removed with a pushing operation and a pull-out operation, a receiving port, a lid that is moved in interconnection with the pushing operation and the pull-out operation to open and close the receiving port, and an engaging portion with which the lid is engaged in the state of closing the receiving port. The powder container includes a protrusion and a disengagement portion. The lid includes a holding portion that removably holds the protrusion, and an engaged portion that is engaged with the engaging portion during the pull-out operation. The powder container is movable in a direction in which the protrusion moves away from the disengagement portion during the pull-out operation.

  • Patent number: 9645526
    Abstract: Provided is a powder containing device including a powder container that contains powder, that has a first end which is closed, that has a second end which is opened, that includes a main body section and a tapered section which is disposed on the second end side from the main body section and has a diameter reduced as close to the second end side, and that has an inner circumferential surface on which a protruding ridge is formed to convey the powder to the second end side by rotating around a rotation axis extending in a direction in which the first end and the second end is connected, and a lid member that is provided with an outlet of the powder, is maintained in a non-rotating state, and causes the powder flowing from the opening to flow out from the outlet.

  • Patent number: 9639029
    Abstract: An image forming apparatus includes an accommodation container, a storage medium, and a controller. The accommodation container includes a rotational portion and outflow portion. The rotational portion accommodates a developer therein and has a helical-shaped transport section formed in an inner surface thereof. The outflow portion rotatably supports the rotational portion and has an outflow port through which the developer transported during rotation of the rotational portion flows out. The storage medium stores use state information of the developer accommodated in the rotational portion. The controller controls a driving source which drives the rotational portion. When a use state of the accommodation container for the developer is a use state which is set in advance, the controller intermittently drives the rotational portion by performing driving at a rotation angle of (n+½)?±18 degrees or less than 90 degrees and stopping.

  • Patent number: 9639028
    Abstract: A container for developer detachably mountable to an image forming apparatus body includes a container body, a discharge member, a resistive member, and a resistance reduction mechanism. The container body contains developer and is rotated when drive is transmitted from the image forming apparatus body. The discharge member supports the container body rotatable relative to the discharge member and has a discharge port through which the developer is discharged. The resistive member is brought into contact with the container body so as to apply resistance to the rotation of the container body. The resistance reduction mechanism changes a contact state between the resistive member and the container body so as to reduce the resistance between the resistive member and the container body when the container is mounted to the image forming apparatus body.

  • Publication number: 20170090347
    Abstract: A detachable body includes an opening portion, an opening and closing member, a sealing member, a sealing member, and a protrusion portion. The opening and closing member is movable between an open position and a closed position. The opening and closing member includes a facing portion that faces the opening portion with a gap when the opening and closing member is located at the closed position. When the opening and closing member is moved to the open position, the sealing member has a thickness that is thicker than a gap between the opening portion and the facing portion. When the opening and closing member is moved to the closed position, the sealing member elastically deforms to seal the opening portion. The protrusion portion protrudes from one of a frame portion around the opening portion and the facing portion toward the other.
