| 20090097876 | Liquid developing apparatus and image forming apparatus - Provided are a liquid developing apparatus and an image forming apparatus, wherein a high-viscosity liquid developer layer is transferred sequentially from a developer supply member to a developer coating member and to the developer carrying member among rollers, and the developer supply width of the developer supply member is made smaller than the width of the developer coating member and greater than the width of the developer carrying member, whereby an occurrence of the area, at the end portions of the developer carrying member, where the volume of developer is uneven is reduced, and the liquid developer is prevented from wrapping around the end faces of the developer coating member, without making the apparatus complicated. | 04-16-2009 |
| 20100040387 | Wet development device, wet development method, and image forming apparatus using the device - The invention provides a wet development device, wet development method and image forming apparatus having the device by which appropriate cleaning can be performed, the wear of the blade or developing roller can be reduced, and good images can be obtained without toner contamination even when the amount of toner for development or that of electric charge of the toner is changed for changing the density or gradation of image or type of paper. The toner in the developer is electrically charged to an arbitral charging amount by a discharging section and provided for the development and the charge of the toner is eliminated after development by that a discharging section is provided before cleaning the developer remaining on the developing roller and the output of the discharging section is appropriately controlled corresponding to the output of the discharging section. | 02-18-2010 |
| 20100124428 | Image forming apparatus and method for image forming - A developing device using a liquid developer removes developer using the contact-rotation between rollers such as a developing roller and thin layer forming roller when an image is not formed, and includes a contact pressure modification section that modifies the contact pressure in the contact region between rollers rotating in contact with one another. When operation is performed to remove the developer using the contact-rotation between rollers with the supply of liquid developer being suspended, modifications are made to ensure that the contact pressure in the contact region is smaller than that during image formation. | 05-20-2010 |
| 20110020023 | TONER CONCENTRATION ADJUSTING SYSTEM AND IMAGE FORMING APPARATUS USING THE SAME - The present invention provides a toner concentration adjusting system and an image forming apparatus which can accurately adjust toner concentration by controlling the supply of a concentrated developer even if a production lot of the concentrated developer is different. In the method, for controlling the toner concentration, in which the supply of the concentrated developer and the like to a wet type developer for which a first control target value is set is controlled while detecting a substitute characteristic of toner concentration, the first control target value is corrected depending on a second control target value based on a substitute characteristic of the toner concentration of the lot of the concentrated developer to be supplied, and depending on a cumulative supply amount of the lot of the concentrated developer. | 01-27-2011 |
| 20110116820 | DEVELOPER CONCENTRATION ADJUSTMENT APPARATUS, METHOD FOR ADJUSTING DEVELOPER CONCENTRATION, AND IMAGE FORMING APPARATUS USING THE SAME - This invention provides a developer concentration adjustment apparatus, a method for concentration adjustment, and an image forming apparatus, in which concentration adjustment is performed by use of a stirring load as a substitute characteristic of viscosity which represents a developer concentration, wherein a trouble of abnormality generation in toner concentration detection due to drying-adhesion of a residual developer on the stirrer is reduced. At the time of finishing the concentration adjustment, a concentration adjustment tank is made to be empty and the stirrer is cleaned by carrier liquid or a liquid developer having a concentration lower than a predetermined concentration. Alternatively, the stirrer is cleaned by empty-stirring operation not being put in a cleaning developer. | 05-19-2011 |

| 20090042962 | Therapeutic Agent for Keratoconjunctival Disorder - An object of the present invention is to research a therapeutic agent for a keratoconjunctival disorder. A compound represented by the following general formula (1) or a salt thereof exhibits an excellent improving effect on corneal disorder models, and therefore is useful as a therapeutic agent for a keratoconjunctival disorder such as dry eyes, corneal ulcer, keratitis or conjunctivitis. In the formula, the ring Y represents a substituted or unsubstituted nitrogen-containing heterocyclic ring; R | 02-12-2009 |
| 20100120873 | PROPHYLACTIC OR THERAPEUTIC AGENT FOR AGE-RELATED MACULAR DEGENERATION - An object of the present invention is to find a novel medicinal use of 2-phenyl-1,2-benzisoselenazol-3(2H)-one or a salt thereof. 2-Phenyl-1,2-benzisoselenazol-3(2H)-one or a salt thereof exhibits an excellent inhibitory effect on neovascularization in the choroid and also has a protective effect on retinal pigment epithelial cell damage, and therefore is useful as a prophylactic or therapeutic agent for age-related macular degeneration. | 05-13-2010 |
| 20110009376 | PROPHYLACTIC OR THERAPEUTIC AGENT FOR EYE DISEASE ACCOMPANIED BY OPTIC NERVE DISORDER - The present invention provides a novel pharmaceutical use of 2-phenyl-1,2-benzisoselenazol-3(2H)-one or a salt thereof. 2-Phenyl-1,2-benzisoselenazol-3(2H)-one or a salt thereof exhibits an excellent suppressive effect on retinal ganglion cell death in a pharmacological test using rats, and is therefore useful as a prophylactic or therapeutic agent for an eye disease accompanied by optic nerve disorder. | 01-13-2011 |
