20080247788 | CYAN TONER, MAGENTA TONER, YELLOW TONER, BLACK TONER, AND FULL-COLOR IMAGE-FORMING METHOD - Provided are a toner containing at least a binder resin and a colorant, the toner having a specific hue angle and an absorbance at a specific wavelength in reflectance spectrophotometry, and a full-color image-forming method involving the use of the toner, the method including the steps of: forming an electrostatic image on a charged electrostatic image bearing member; developing the formed electrostatic image with the toner to form a toner image; transferring the formed toner image onto a transfer material; and fixing the transferred toner image to the transfer material to form a fixed image. | 10-09-2008 |
20080298860 | IMAGE FORMING APPARATUS - An image forming apparatus includes a toner image forming unit for effecting an image forming operation to form toner image on a recording material, wherein the toner image comprises chromatic toner image components with different colors and a transparent toner image component overlaid thereon; a fixing unit for effecting a fixing operation to heat and fix the toner image on the recording material; a switching unit for switching, in accordance with information relating to a maximum toner amount per unit area in a zone in which the transparent toner component is present, operations to a mode in which the formation of the toner image is effected through a plurality of such image forming operations, and the fixing of the toner image is effected through a plurality of such fixing operations. | 12-04-2008 |
20090097889 | IMAGE FORMING APPARATUS, IMAGE FORMING CONTROL METHOD, AND RECORDING MEDIUM RECORDING IMAGE FORMING CONTROL PROGRAM - An image forming apparatus that includes an image forming component, a flash fixing component and a control component is provided. The image forming component forms toner images using at least two toners respectively having different colors and transfers the formed toner images onto a recording medium. The flash fixing component emits a flash light onto the recording medium onto which the toner images have been transferred by the image forming component and fixes the toner images. The control component that controls the image forming component to form the toner images so that, among the toner images, a second color toner is adhered to a surface of a toner layer formed by a first toner color at a region at which the toner layer formed by the first toner color is formed, the absorbance of the second color toner being lower than that of the first color toner. | 04-16-2009 |
20090257793 | IMAGE FORMING APPARATUS - The image forming apparatus includes an image forming portion forming a toner image on a recording material, and a fixing portion heating and fixing the toner image formed on the recording material to the recording material, wherein the apparatus has a cleaning mode in which the fixing portion is cleaned, and when the cleaning mode is set, the image forming portion forms a predetermined toner image on the recording material, and the fixing portion then heats and fixes the predetermined toner image to the recording material to form a cleaning sheet which is heated and conveyed to clean the fixing portion. By the virtue of the present invention, it achieves high cleaning performance in which the fixing portion is cleaned by the cleaning sheet. | 10-15-2009 |
20100150620 | METHOD AND APPARATUS FOR PRINTING USING A TANDEM ELECTROSTATOGRAPHIC PRINTER - A tandem color electrostatographic printer apparatus has five or more color printing stations or modules for applying respective color separation toner images to a receiver member to form a pentachrome color image in a single pass. A fuser station fuses the pentachrome color image. A clear toner overcoat is then applied to the fused pentachrome toner image and enhanced glossing of the image is provided by a belt glosser to improve color gamut. | 06-17-2010 |
20130011171 | IMAGE FORMING APPARATUS WITH FIXING UNIT - An image forming apparatus including multiple imaging units and a fixing unit is provided. Each of the imaging units includes an image bearing member, a developing device containing a toner including a pressure-induced phase transition resin or a thermoplastic resin, a transfer device, and an image bearing member cleaner, and is adapted to form a toner image with the toner. The fixing unit includes a pressure fixing device adapted to fix the toner including the pressure-induced phase transition resin on the recording medium by applying a temperature Tb and a pressure Pb thereto in a pressure fixing nip, and a heat fixing device adapted to fix the toner including the thermoplastic resin on the recording medium by applying a temperature Ta and a pressure Pa thereto in a heat fixing nip. The image forming apparatus satisfies the following inequations: TbPa. | 01-10-2013 |
20140356035 | IMAGE FORMING APPARATUS - An image forming apparatus includes: a first image forming section that forms a first image using a first toner containing flat pigment particles; a second image forming section that forms a second image using a second toner not containing the flat pigment particles; and a fixing section that fixes the first image to a recording medium with a quantity of heat that is smaller than that for a case where the fixing section fixes a third image not including the first image but including the second image. | 12-04-2014 |
20140369723 | IMAGE-FORMING APPARATUS - An image-forming apparatus includes an image unit that forms an image using at least one of a white toner and a color toner having a lower storage modulus than the white toner and a fixing unit that fixes the image to a medium with heat. A time P calculated by subtracting a fixing time for which an image of the color toner alone is fixed to normal paper used as the medium from a fixing time for which an overlaid image of the white toner and the color toner is fixed to color paper used as the medium is more than 0 ms and less than 30 ms. | 12-18-2014 |
20160033886 | TONER SET FOR PRINTING SYSTEM AND PRINTING SYSTEM - A toner set is used in a printing system that is capable of recycling a print medium and includes a first image forming portion which forms a toner image on the medium with a decolorable toner which is decolored by being heated at a temperature T | 02-04-2016 |
