20090123866 | Method For Producing Toner - A method for producing toner is described. In the method for producing a toner, a resin liquid is prepared by mixing at least a binder resin made of polyester resin and a colorant with an organic solvent, the resin liquid is dispersed in an aqueous medium to form an emulsion, and the organic solvent is removed from the emulsion to produce a toner. The organic solvent before preparation of the resin liquid contains 5 to 20 parts by weight of water per 100 parts by weight of the organic solvent. | 05-14-2009 |
20090142102 | Image Forming Apparatus - Each transport electrode has its longitudinal direction intersecting with a sub-scanning direction. Transport electrodes | 06-04-2009 |
20090162106 | Image Forming Device - An image forming apparatus includes a developer containing casing, a developer transport body, transport electrodes, and a developer vibrating section. The developer containing casing is a box-like member in which a developer is contained. The developer transport body has a developer transport surface, and is disposed within the developer containing casing. The plurality of transport electrodes are provided along the developer transport surface. These transport electrodes are configured such that they can transport the developer in a predetermined developer transport direction on the developer transport surface upon application of traveling-wave voltages. The developer vibrating section is configured to be able to vibrate the developer which is to be transported on the developer transport surface. | 06-25-2009 |
20090191477 | Method For Producing Toner - Provided is a method for producing a toner including the steps of: preparing a resin liquid by mixing at least a binder resin made of polyester resin and a colorant with an ester organic solvent represented by the following general formula (1); dispersing the resin liquid in an aqueous medium to form an emulsion; and removing the ester organic solvent from the emulsion to produce a toner, in which the ester organic solvent before the preparation of the resin liquid contains water in an amount of not less than 1% by weight and up to the saturation solubility at 25° C. to the ester organic solvent. | 07-30-2009 |
20100247166 | Image Forming Apparatus - Each transport electrode has its longitudinal direction intersecting with a sub-scanning direction. Transport electrodes are disposed in parallel with each other and are arrayed along the sub-scanning direction. A transport-electrode electricity supply wiring section is connected to root portions of the transport electrodes. The root portions are one end portions of the transport electrodes with respect to the longitudinal direction. Toner transport guide members are disposed to cover the transport-electrode electricity supply wiring section and opposite end portions of the transport electrodes; i.e., the root portions and distal end portions. | 09-30-2010 |
20130287445 | Developing Apparatus and Image Forming Apparatus - A developing apparatus is provided, including a developing unit including a developing roller; a developer accommodating unit; a partition wall partitioning the developing unit and the developer accommodating unit; a supply port which makes communication between the developing unit and the developer accommodating unit; a transport member configured so that the developer accommodated in the developer accommodating unit is supplied to the developing unit via the supply port in accordance with rotation; a return port configured so that the developer contained in the developing unit is permitted to fall into the developer accommodating unit; an opening/closing member configured to be movable between an open position for opening the return port and a closed position for closing the return port; and a driving mechanism configured so that the opening/closing member is moved to the closed position and the open position. | 10-31-2013 |
