A developer container includes: an accommodating portion which has a first frame and a second frame and is configured to accommodate a developer; and a conductive sheet. The second frame has a joining surface for joining the second frame to the conductive sheet, the first frame and the second frame share an uneven fitting portion where the first frame and the second frame fit with each other in a direction of intersecting the joining surface, the uneven fitting portion has a contact face where the first frame and the second frame are being in contact with each other, a gap is formed by the first frame, the second frame and the conductive sheet, and the contact face is a face facing the gap and being disposed in a direction along the joining surface.

Developer container, developing apparatus, process cartridge, image forming apparatus, and manufacturing method of developer container

A structure includes a rotatable rotating member, a blade, a support member, and a frame body. The blade extends in an axial direction of the rotating member and is in contact with or disposed close to a surface of the rotating member. The support member supports the blade such that one end side of the blade projects toward the rotating member in a lateral direction that intersects the axial direction. The frame body is formed by insert molding in which resin is injected while the support member is secured to a mold. The frame body clamps part of the support member so as to support the support member.

Image forming apparatus with frame body and detachable cartridge with integrated photosensitive drum

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.

Developer accommodating unit, process cartridge, and electrophotographic image forming apparatus

A developing unit includes: a frame; a flexible container, provided inside the frame, for accommodating a developer, wherein the flexible container includes an opening for permitting discharge of the developer; an urging member, provided inside the frame, for urging the flexible container to deform the flexible container; and a developer carrying member for carrying the developer discharged from the opening of the flexible container. The flexible container includes a projected portion projecting toward an outside of the flexible container. The projected portion is moved depending on deformation of the flexible container, by urging of the flexible container, to stir the developer discharged from the opening.

Developing unit, process cartridge and image forming apparatus

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.

Developer accommodating container, process cartridge and electrophotographic image forming apparatus

A developer accommodating unit for accommodating a developer includes: a flexible container provided with a plurality of openings for permitting discharge of developer. The openings are formed and arranged in a longitudinal direction of the developer accommodating unit. The openings have opening areas such that with respect to the longitudinal direction, the opening area of the opening provided at an end portion is larger than the opening area of the opening provided at a central portion.

Developer accommodating unit, developing device, process cartridge and image forming apparatus

A developer accommodating container for accommodating a developer includes; an opening for permitting discharge of the developer; and a sealing member, mounted on the developer accommodating container, capable of exposing the opening by being moved. At least a part of the sealing member is formed of a material having compatibility with a material for forming the developer accommodating container and a material having incompatibility with the materiel for forming the developer accommodating container. Either one of the material having the compatibility and the material having the incompatibility is dispersed in the other one of the materials.

Developer accommodating container, developer accommodating unit, process cartridge and image forming apparatus

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.

Developer accommodating unit, manufacturing method thereof, process cartridge and image forming apparatus

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.

Developer accommodating unit, process cartridge and electrophotographic image forming apparatus

A developer accommodating unit includes: a flexible container, provided with an opening for permitting discharge of a developer, for accommodating the developer; a frame for accommodating the flexible container and for accommodating the developer discharged from the flexible container; and an urging member, provided inside the frame, for urging the flexible container to deform the flexible container. The flexible container has a plurality of sides including an opening-containing side and another side having stiffness lower than that of the opening-containing side.

Developer accommodating unit with a urging member for urging a flexible member

An exposure apparatus comprises a component configured to project a pattern of an original onto a substrate, a structure configured to support the component, a support configured to support the structure, a gas spring which is located between the structure and the support and configured to support the structure, and a stopper accommodated in an internal space of the gas spring so as to prevent the structure from moving relative to the support in excess of an allowable level.
