20090003872SEALING MEMBER, TONER ACCOMMODATING CONTAINER AND IMAGE FORMING APPARATUS - A toner container detachably mountable to an image forming apparatus, includes a main body for containing toner; a sealing portion for sealing the toner discharge opening; locking projections for snap fitting engagement with holes provided in a cylindrical member of an image forming apparatus, wherein the projections receive from the cylindrical member unsealing forces for unsealing the toner discharge opening by a relative movement between the sealing portion and the toner container, wherein a number of the locking projections is larger than a number of ribs provided between the holes of the cylindrical member.01-01-2009
20090129825DEVELOPER SUPPLY CONTAINER AND DEVELOPER SUPPLY SYSTEM - A developer supply container detachably mounts to a developer receiving apparatus and supplies a developer by rotation and includes a regulation portion for determining whether or not the developer supply container should be mounted by being regulated by a regulation member of the developer receiving apparatus and a lead portion which is movable relative to a guiding portion of the developer receiving apparatus so that the regulation member and the regulation portion are in phase with each other. When the developer supply container is inserted in a direction of a rotation axis thereof, a phase of the regulation portion with the regulation member is determined by movement of the lead portion of the developer supply container relative to the guiding portion of the developer receiving apparatus and then is regulated by the regulation member.05-21-2009
