Abstract
A developer accommodating container and a developing device that require less force to pull out a sealing member thereby to permit easier opening of the developer accommodating container. The developer accommodating container includes a container main body for accommodating a developer, the container main body having an opening through which the developer is supplied to a development container; and a sealing member which seals the opening and can be pulled out, the sealing member having a sealant surface fixed to the container main body; wherein the sealing member is pressed by an end seal provided on an end on a side, from which the sealing member is pulled out, to prevent the developer adhering to the sealing member from leaking out when the sealing member is pulled out, and a surface of the sealing member which is provided with the sealant surface that has an area with a friction coefficient smaller than that of the sealant surface, the area being located in a portion that comes in contact with the end seal at the beginning of pulling out the sealing member.
