Patent number: 9639028Abstract: 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.Type: GrantFiled: July 22, 2015Date of Patent: May 2, 2017Assignee: FUJI XEROX CO., LTD.Inventors: Kiyohito Horii, Seigo Shinozaki, Makoto Kanno, Shota Oba, Norihiro Tamazawa, Ayumi Noguchi, Shigeru Inaba, Shinichiro Fujimori

Patent number: 9639029Abstract: 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.Type: GrantFiled: January 15, 2016Date of Patent: May 2, 2017Assignee: FUJI XEROX CO., LTD.Inventors: Ayumi Noguchi, Shota Oba, Norihiro Tamazawa, Makoto Kanno, Seigo Shinozaki, Keisuke Kubo
