20130164039 | DEVELOPER ACCOMMODATING CONTAINER, 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. | 06-27-2013 |
20140029974 | DEVELOPER ACCOMMODATING UNIT, PROCESS CARTRIDGE, ELECTROPHOTOGRAPHIC IMAGE FORMING APPARATUS - 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. | 01-30-2014 |
20140064793 | DEVELOPING UNIT, PROCESS CARTRIDGE AND 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. | 03-06-2014 |
20140072330 | DEVELOPER ACCOMMODATING UNIT, PROCESS CARTRIDGE AND ELECTROPHOTOGRAPHIC 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. | 03-13-2014 |
20140072331 | DEVELOPER ACCOMMODATING CONTAINER, DEVELOPER ACCOMMODATING UNIT, 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. | 03-13-2014 |
20140199093 | DEVELOPER ACCOMMODATING CONTAINER, PROCESS CARTRIDGE AND ELECTROPHOTOGRAPHIC 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. | 07-17-2014 |
20140199096 | DEVELOPER ACCOMMODATING UNIT, DEVELOPING DEVICE, PROCESS CARTRIDGE AND 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. | 07-17-2014 |
20150234319 | DEVELOPER ACCOMMODATING UNIT, MANUFACTURING METHOD THEREOF, 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. | 08-20-2015 |
