20130336679 | DEVELOPER CONTAINING UNIT, PROCESS CARTRIDGE, AND ELECTROPHOTOGRAPHIC IMAGE FORMING APPARATUS - A developer containing unit configured to contain a developer, the developer containing unit including: a flexible container configured to contain the developer and provided with an opening portion through which the developer is discharged; a frame configured to accommodate the flexible container; a pressure member provided in the frame and configured to deform the flexible container; and an abutment portion extending in a longitudinal direction of the frame and at which the flexible container and the frame abut against each other. | 12-19-2013 |
20130343785 | DEVELOPER ACCOMMODATING UNIT, PROCESS CARTRIDGE AND ELECTROPHOTOGRAPHIC IMAGE FORMING APPARATUS - A developer accommodating unit for accommodating a developer for image formation includes a flexible container provided with an opening | 12-26-2013 |
20140016961 | DEVELOPER ACCOMMODATING CONTAINER, PROCESS CARTRIDGE, ELECTROPHOTOGRAPHIC IMAGE FORMING APPARATUS - A developer accommodating container for accommodating a developer includes a developer bag | 01-16-2014 |
20140072329 | DEVELOPER ACCOMMODATING UNIT - A developer accommodating unit for accommodating a developer includes: a flexible container, provided with an opening for permitting discharge of the developer, for accommodating the developer; and a frame. The flexible container is provided with a fastening hole for fastening said flexible container in said frame. The frame includes a fixing shaft portion fixed in the fastening hole by being inserted into the fastening hole and includes a retaining portion for preventing the fixing shaft portion from being disengaged from the fastening hole. The fastening hole is locked by fitting the fastening hole around the fixing shaft portion while an edge of the fastening hole rides over the retaining portion by elastic deformation thereof. | 03-13-2014 |
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 |
20140072346 | DEVELOPER ACCOMMODATING CONTAINER, PROCESS CARTRIDGE AND IMAGE FORMING APPARATUS - A developer accommodating container for accommodating a developer for image formation, includes a first flexible member having a three-dimensional shape; a second flexible member for forming a space for accommodating the developer by covering a part of the first flexible member; wherein the developer accommodating container is constituted by bonding the first flexible member and the second flexible member to each other, and an injection opening, provided between the first flexible member and the second flexible member, for permitting injection of the developer into the developer accommodating container. An adjacent side, which is one of sides constituting an outer configuration of the three-dimensional shape and which is adjacent to the injection opening, has an angle of less than 90 degrees with respect to an injection direction of the developer at the injection opening. | 03-13-2014 |
20140072347 | DEVELOPER ACCOMMODATING CONTAINER, PROCESS CARTRIDGE AND IMAGE FORMING APPARATUS - A developer accommodating container for accommodating a developer for image formation, comprising: a first flexible member having a three-dimensional shape; a second flexible member for forming a space for accommodating the developer by covering a part of the first flexible member; wherein the developer accommodating container is constituted by bonding the first flexible container and the second flexible container to each other, and an injection opening, provided between the first flexible container and the second flexible container, for permitting injection of the developer into the developer accommodating container. An adjacent portion adjacent to the injection opening in the three-dimensional shape has a folded shape. When the injection opening is opened, the adjacent portion expands in a direction including, a directional component perpendicular to an injection direction of the developer at the injection opening. | 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 |
20140363196 | DEVELOPER ACCOMMODATING UNIT, DEVELOPING DEVICE, PROCESS CARTRIDGE AND IMAGE FORMING APPARATUS - 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. | 12-11-2014 |
