Abstract
A developer accommodating container includes: a flexible container provided with an opening for permitting discharge of a developer; a sealing member, mounted to the flexible container in a state in which the sealing member seals the opening, capable of exposing the opening by being wound up; an unsealing member for winding up the sealing member by being rotated to expose the opening; a frame for accommodating the unsealing member; and a limiting portion for limiting deformation of the unsealing member with respect to a direction of a force applied from the sealing member to the unsealing member when the unsealing member winds up the sealing member.
