Patent number: 8781374Abstract: A developer storage body includes an outer case enclosing a space in which a developer is stored and having a first opening, and an inner case rotatably provided in the outer case and having a second opening. The inner case is rotatable with respect to the outer case between an opening position and a closing position to open and close the first opening. An operating portion is provided for operation to rotate the inner case between the opening and closing positions. The inner case includes a bottom wall having the second opening, and a plurality of beams provided so as to extend between edges of the bottom wall. The beam has an inclined upper surface. The inclined upper surface is inclined downward in a gravity direction toward a side end of the beam in a cross-section of the beam.Type: GrantFiled: May 13, 2011Date of Patent: July 15, 2014Assignee: Oki Data CorporationInventor: Osamu Teramura

Patent number: 8116666Abstract: A toner container holds toner and is detachably attached to an image forming apparatus. A housing holds the toner therein and includes a first engagement portion and an opening through which the toner is discharged into the image forming apparatus. The first engagement portion includes a first surface and either a first projection formed on the first surface or a first recess formed in the first surface. A shutter is fitted into the housing and is slidable relative to the housing. The shutter includes a second engagement portion that engages the first engagement portion when the shutter slides relative to the housing. The second engagement portion includes a second surface. Either a second projection is formed on the second surface or a second recess is formed in the second surface.Type: GrantFiled: February 13, 2008Date of Patent: February 14, 2012Assignee: Oki Data CorporationInventor: Osamu Teramura

Patent number: 8116642Abstract: A developer stirring unit, a developing device containing the developer stirring unit and an image forming apparatus comprising the developing device are supplied capable of correctly judging a remainder amount of developer in accommodating tank. In the developer stirring unit, a accommodating tank accommodates developer; a stirring member has at least one shaft portion and is used to stir the developer accommodated in the accommodating tank; a bearing member couples with the shaft portion and supports the stirring member to possibly rotate around the shaft portion serving as rotation axis and to possibly move along a axis direction of the rotation axis; a driving section drives the stirring member to rotate; and a judging section judges a remainder amount of the developer in the accommodating tank, wherein the stirring member is controlled to move along an axis direction of the rotation axis together with rotating along a rotation direction of the rotation axis.Type: GrantFiled: January 30, 2009Date of Patent: February 14, 2012Assignee: Oki Data CorporationInventor: Osamu Teramura

Patent number: 5790920Abstract: A toner image processing apparatus performs a printing operation and a cleaning operation. A toner-attracting electrode includes first and second electrodes disposed closer to the charged surface of a photosensitive drum and outside of a path through which the light from the exposing device illuminates the charged surface. During the toner attracting operation, a toner-recovering device causes the toner-attracting electrode to attract the toner particles floating in the air surrounding the exposing device, and reversely charged toner particles and residual toner particles left on the photosensitive drum after the toner image is transferred to the print medium. During the toner-releasing operation, the toner-recovering device causes the toner-attracting electrode to release the attracted toner particles to the photosensitive drum. The toner-attracting operation is performed during the printing operation and the toner-releasing operation is performed during the cleaning operation.Type: GrantFiled: July 14, 1997Date of Patent: August 4, 1998Assignees: Oki Data System Co., Ltd., Oki Data Corp.Inventors: Osamu Teramura, Hiroyuki Yajima
