Abstract: A cartridge includes a rotating body, a blade that extends in an axial direction of the rotating body and is disposed on the rotating body, a supporting member that is fixed to the blade and configured to support the blade in such a manner that the blade protrudes toward the rotating body in a shorter direction crossing the axial direction, a frame body including a placing surface that supports the supporting member, and a fixed portion that is disposed on the placing surface via the supporting member and fixed to the frame body. The supporting member includes a cut portion extending in the axial direction. The fixed portion includes a deformed portion deformed by given energy, and the deformed portion engages with the cut portion so that movement of the supporting member with respect to the frame body is restricted.

Abstract: A developer accommodating unit for accommodating a developer for image formation. A flexible container includes a developer accommodating portion for accommodating the developer and an opening for permitting discharge of the developer. The flexible container also includes a superposed multi layer sheet structure portion for forming the developer accommodating portion. A sealing member seals the opening and an unsealing member moves the sealing member to unseal the opening. A frame that accommodates the flexible container, the sealing member, and the unsealing member includes a fixing portion for fixing the flexible container. A fixed portion fixed to the fixing portion is provided at the superposed multi layer sheet structure portion of the flexible container, and an interlayer bonding portion between the superposed layers is provided between the fixed portion of the multi layer sheet structure portion and the developer accommodating portion.

Abstract: A cartridge includes a rotating body, a blade that extends in an axial direction of the rotating body and is disposed on the rotating body, a supporting member that is fixed to the blade and configured to support the blade in such a manner that the blade protrudes toward the rotating body in a shorter direction crossing the axial direction, a frame body including a placing surface that supports the supporting member, and a fixed portion that is disposed on the placing surface via the supporting member and fixed to the frame body. The supporting member includes a cut portion extending in the axial direction. The fixed portion includes a deformed portion deformed by given energy, and the deformed portion engages with the cut portion so that movement of the supporting member with respect to the frame body is restricted.

Abstract: A developer accommodating container for accommodating a developer includes: a flexible container provided with an opening for permitting discharge of the developer; a sealing member for sealing the opening in a state in which the sealing member is bonded to a periphery of the opening, wherein the sealing member is capable of exposing the opening by being removed by pulling; and a reinforcing portion, provided at least as a part of the periphery of the opening, for decreasing a degree of deformation of the opening.

Abstract: A developer accommodating unit includes: a flexible container, provided with an opening for permitting discharge of a developer, for accommodating the developer; and a frame for accommodating the flexible container and for accommodating the developer discharged from the flexible container. The flexible container includes a projected portion projected from a part of a side forming the flexible container toward an outside of or toward an inside of the flexible container.

Abstract: A developer accommodating unit includes: a developer bag in which a developer is incorporated. The developer bag includes: a filling port for filling the developer; a filling region where the developer is filled; a non-filling region, provided outside the filling region, where the developer is not filled, and a folded portion formed by folding the filling region and the non-filling region. The folded portion includes a welding portion.

Abstract: A developer accommodating unit includes: a flexible container including an opening for permitting discharge of a developer; a sealing member for forming a bonding portion between itself and the flexible container; an unsealing member; and an accommodating container. The bonding portion includes a first bonding portion extending in a longitudinal direction of the sealing member at a periphery of the opening in an upstream side of a peeling direction of the sealing member, a second bonding portion extending in the longitudinal direction at the periphery of the opening in a downstream side of the peeling direction, and a third bonding portion bonded upstream of the first bonding portion with respect to the peeling direction. When the sealing member exposes the opening, the bonding portion is peeled in the order of the third bonding portion, the first bonding portion and the second bonding portion.

Abstract: A developer accommodating unit for accommodating a developer includes: an accommodating portion, provided with an opening, for accommodating the developer; a sealing member for sealing the opening; and an unsealing member rotatable for winding up the sealing member. The sealing member is peelable off from the accommodating portion to unseal the opening in a first unsealing direction and a second unsealing direction opposite to the first unsealing direction.
