Publication number: 20160259267Abstract: 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: ApplicationFiled: July 22, 2015Publication date: September 8, 2016Applicant: FUJI XEROX CO., LTD.Inventors: Kiyohito HORII, Seigo SHINOZAKI, Makoto KANNO, Shota OBA, Norihiro TAMAZAWA, Ayumi NOGUCHI, Shigeru INABA, Shinichiro FUJIMORI
