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 |
20090175640 | Apparatus for forming multi-color image with control of unintended reverse-transfer of developer image onto photoconductor - An apparatus for forming a multi-color is disclosed which includes a controller that performs an anti reverse-transfer control such that a surface potential of a previously-formed separated-developer-image subset of a plurality of single-color separated-developer-images which has been previously transferred onto an image transferred medium is reduced, prior to a subsequent transfer in which a remainder of the plurality of separated-developer-images is transferred onto the image transferred medium after a previous transfer of the previously-formed separated developer-image subset onto the image transferred medium, to thereby prevent a reverse transfer of a part of a developer material on the image transferred medium from the image transferred medium onto a photoconductor at the subsequent transfer. | 07-09-2009 |

20100247158 | Developer Supply Device and Image Forming Apparatus - An apparatus includes an upstream transport surface TSa which, while facing a circumferential surface DS of a developing roller, is disposed upstream of an area (developing area) in the vicinity of a latent image forming surface LS, and a downstream transport surface TSb which, while facing the circumferential surface, is disposed downstream of the developing area. The apparatus forms electric fields on the upstream and downstream transport surfaces for moving a charged developer T from an upstream side toward a downstream side. In the apparatus, the transport speed of developer on the upstream transport surface is higher than that on the downstream transport surface. As a result, there can be lowered a speed at which the developer which has not adhered to the circumferential surface and has reached a downstream end portion of the upstream transport surface flies out toward the vicinity of the developing area. Also, there can be avoided a problem in that the developer stagnates at an upstream end portion of the downstream transport surface with a resultant hindrance to collection of the developer. | 09-30-2010 |
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 |
20140178093 | Developing Device, Process Cartridge and Image Forming Apparatus - A developing device includes a casing configured to accommodate developer, a developing roller, a seal member, at least portion of which is disposed between the developing roller and the casing, and which includes a fabric member including a plurality of first fibers extending in a first direction, and a heat radiation member configured to contact end surfaces of the first fibers of the seal member and radiate heat of the seal member. | 06-26-2014 |
