Image forming apparatus and container for developer

摘要

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.

1. A container for developer detachably mountable to an image forming apparatus body, the container comprising:
a container body configured to contain developer and configured to be rotated about an axial direction when drive is transmitted from the image forming apparatus body; a discharge member that supports the container body rotatable relative to the discharge member and that has a discharge port configured to discharge the developer; a resistive member configured to be brought into contact with the container body so as to apply resistance to the rotation of the container body; and a resistance reduction mechanism configured to change 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, wherein the resistance reduction mechanism includes an opening and closing member supported so as to be movable between an open position, where the opening and closing member opens the discharge port, and a closed position, where the opening and closing member closes the discharge port, by moving parallel to the axial direction of the container body, and wherein the resistive member is supported by the opening and closing member.
