20120045227 | IMAGE FORMING APPARATUS AND IMAGE PROCESSING DEVICE - An image forming apparatus includes: an image information input section into which image information is input, and image holding members by which toner images of two or more colors including black and clear colors are held, respectively. The image forming apparatus further includes a transfer-receiving material to which toner of all colors are transferred from their respective image holding members, an image-area pinpointing section wherein an area of clear toner image to be superposed on a linear image region to be formed with toner of the black color is pinpointed in the image information input into the image information input section, and an image processing section wherein is performed replacement processing that at least part of black image on the pinpointed image area is formed with a hybrid of two or more kinds of colored toner instead of black toner. | 02-23-2012 |
20140119756 | IMAGE FORMING APPARATUS, NON-TRANSITORY COMPUTER READABLE MEDIUM, AND IMAGE FORMING METHOD - An image forming apparatus includes an image forming unit, a density-corrected image forming unit, a measurement unit, an image correction unit, and a fixing unit. The image forming unit forms an image represented by image data as a toner image. The density-corrected image forming unit forms a density corrected image. The measurement unit measures the density of the density corrected image. The image correction unit performs image correction such that a non-halftone image is formed as a halftone image whose halftone percentage is less than 100%. The fixing unit, in a case where the image correction unit performs image correction for image data, fixes a toner image on a recording medium with at least one of an increased fixing temperature, an increased fixing time period, and an increased fixing pressure, the toner image being based on the image data for which image correction has been performed. | 05-01-2014 |
20140248068 | TRANSFER DEVICE AND IMAGE FORMING APPARATUS - A transfer device includes an intermediate transfer belt that is stretched by multiple rollers, and transports a toner image on an outer peripheral surface, a second transfer member that performs second transfer that transfers the toner image to a recording medium at a second transfer position, an opposed member that abuts an inner peripheral surface of the intermediate transfer belt, and is opposed to the second transfer member at the second transfer position, and an abutment member that is rotatably arranged so as to contact the inner peripheral surface of the intermediate transfer belt at a contact point, the contact point being located on the second transfer member side of a region defined by an imaginary line extended orthogonally to an imaginary normal, the imaginary normal connecting a center of the opposed member and a center of the second transfer member at the second transfer position. | 09-04-2014 |
20140356008 | IMAGE FORMING APPARATUS - An image forming apparatus includes: a first image forming section that uses a toner containing flat pigment particles; a second image forming section that uses a toner not containing the flat pigment particles; and a fixing section that fixes an image formed on a recording medium to the recording medium using heat. The quantity of heat that the fixing section applies to the image is increased in the case where the image formed on the recording medium using the toner containing the flat pigment particles is to be fixed compared to a case where the image formed on the recording medium using the toner not containing the flat pigment particles is to be fixed. | 12-04-2014 |
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 |
20150205229 | IMAGE FORMING APPARATUS - An image forming apparatus includes an endless transfer member, a first transfer section, a second transfer section, and a medium transfer section. An image is transferred to the transfer member during circulation of the transfer member. The first transfer section forms an image using a toner containing flat metallic pigment particles, and transfers the formed image to the transfer member through a transfer current. The second transfer section forms an image using a toner not containing flat metallic pigment particles, and transfers the formed image to the transfer member through a transfer current. The second transfer section is disposed upstream of the first transfer section in a circulation direction of the transfer member. The medium transfer section transfers the image transferred to the transfer member to a recording medium through a transfer current. The transfer current for the first transfer section is smaller than that for the second transfer section. | 07-23-2015 |
20150212458 | IMAGE FORMING APPARATUS - An image forming apparatus includes a first image forming portion that forms a toner image on a latent image carrier with a toner containing a flat pigment; and a second image forming portion that forms a toner image on a latent image carrier with a toner not containing the flat pigment. The toner images formed by these image forming portions are transferred to a toner image carrier or a recording medium. The average charge amount per particle of the toner containing the flat pigment is smaller than that of the toner not containing the flat pigment. A transfer width is larger than the particle diameter of the toner containing the flat pigment. A transfer current flowing between the latent image carrier of the second image forming portion and the toner image carrier or the recording medium is higher than or equal to a value required to form an electric field. | 07-30-2015 |
