Each development device comprises a development roller for forming a toner image on a surface of the ... 03/01/07 - 20070048019 - Coupling structure usable with image forming apparatus A coupling structure usable with an image forming apparatus which includes a hopper frame to accommodate toner and an agitator, a development frame coupled to the hopper frame and installed with a developing roller and a supply roller to supply the toner to the developing roller, a plurality of gears ... 03/01/07 - 20070048018 - Power transmitting device for developing device and image forming apparatus with the same A power restricting device for a developing device of an image forming apparatus and an image forming apparatus with the same are disclosed. The power restricting device for a developing device of an image forming apparatus includes a driving section with at least one rotational member which is rotated by ... 02/22/07 - 20070041747 - Image forming apparatus having vibration reducing member An image forming apparatus having a vibration reducing member is provided. The image forming apparatus includes a photosensitive member, a developing roller, an axis of the developing roller, and a gear train for driving the developing roller. Accordingly, the quality of print image is improved by providing the vibration reducing ... 12/21/06 - 20060285882 - Method for forming image and image forming apparatus The developing agent is selected to have a distribution of adhesive force to the surface of an image carrier, which is configured such that the ratio of the developing agent having an adhesive force which is not less than 2.5 times as high as an average value of a distribution ... 03/09/06 - 20060051134 - Method of driving device for driving developers and image forming apparatus having the device for driving developers A method of driving a device for driving developers and an image forming apparatus having the device for driving developers are provided. In a two-pass image forming apparatus having two photosensitive media, one or two driving sources are driven by forward and backward rotation to drive two developers disposed around ... 01/19/06 - 20060013618 - Developing device, developing cartridge, process cartridge, and image forming apparatus using these Disclosed are a developing device, a developing cartridge, a process cartridge, and an image forming apparatus in which image deficiency is prevented by absorbing the tolerance of each component and making the position of the developing roller in the thrust direction constant and which are easy to assemble. A frame ... 01/05/06 - 20060002741 - Contact pressure setting method and image forming apparatus A contact pressure setting method of setting a contact pressure between contact members of an image forming apparatus. A film member is inserted into a gap between the contact members and the contact pressure is set so that a pulling force to pull out the film member lies within a ... 11/03/05 - 20050244191 - Developer and electrophotographic image forming apparatus having the same A developer includes a developer frame in which a developing agent is contained, a development roller that is rotatably disposed inside the developer frame. Coupling means couples the development roller to the developer frame. The coupling means includes a gear member that is rotatably mounted to the developer frame and ... 08/18/05 - 20050180779 - Developing device, image forming apparatus, image forming system, and method of manufacturing developing device A developing device is provided with: a developer containing section that is for containing a developer and that has a predetermined coefficient of thermal expansion; a developing roller for bearing the developer contained in the developer containing section; a roller-supporting member that is for rotatably supporting the developing roller, that ... ### FreshPatents.com Support - Terms & Conditions |
