20100025918 | SHEET CONVEYING APPARATUS AND IMAGE FORMING APPARATUS - There are provided a sheet conveying apparatus and an image forming apparatus, which enable stable sheet conveyance without depending on sheet size. | 02-04-2010 |
20100171406 | ELECTROCONDUCTIVE LAMINATE - To provide an electroconductive laminate which has a broad transmission/reflection band and which is excellent in electrical conductivity (electromagnetic wave shielding properties), visible light transmittance, visible light antireflection properties, near infrared shielding properties and moisture resistance, and an electromagnetic wave shield for a plasma display employing such a laminate. | 07-08-2010 |
20100278574 | IMAGE FORMING APPARATUS - A before-toner-fixation conveying guide is provided between a transfer portion configured to transfer a toner image, which is formed by an image forming portion, onto a sheet and a fixing portion configured to fix the toner image, which is transferred on the sheet by the transfer portion, to the sheet. The before-toner-fixation conveying guide guides the sheet, on which the toner image is transferred, to the fixing portion. A plurality of consecutive chevron shapes are formed, along a direction orthogonal to a sheet conveying direction, in an end portion on a downstream side in the sheet conveying direction of the before-toner-fixation conveying guide. | 11-04-2010 |
20100327519 | SHEET CONVEYING APPARATUS AND IMAGE FORMING APPARATUS - A sheet conveying apparatus and an image forming apparatus are provided which can prevent the collision of the side end of a sheet with the upstream end in the sheet conveying direction of an abutment reference member. The sheet conveying speed of a pair of conveying rollers | 12-30-2010 |
20110260395 | SHEET CONVEYING APPARATUS AND IMAGE FORMING APPARATUS - There are provided a sheet conveying apparatus and an image forming apparatus, which enable stable sheet conveyance without depending on sheet size. | 10-27-2011 |
20120087687 | IMAGE FORMING APPARATUS - An image forming apparatus may include a transfer nip, a first conveyance belt, a second conveyance belt, a fixing nip, a fixing drive unit, and a control unit. The first conveyance belt conveys the sheet to which a toner image is transferred and fixed. The fixing drive unit drives the fixing nip so that the fixing nip conveys the sheet at a speed that is higher than the transfer speed in a high speed fixing mode in which the fixing nip fixes the toner image to the sheet while conveying the sheet. The control unit sets a circumferential speed of the first conveyance belt and a circumferential speed of the second conveyance belt so that the sheet bridging the first and second conveyance belts is pulled by the second conveyance belt to slide on the first conveyance belt in the high speed fixing mode. | 04-12-2012 |
20120091653 | SHEET CONVEYING APPARATUS AND IMAGE FORMING APPARATUS - A skew feeding correction portion includes a first pair of skew-feed rollers that has rollers, a second pair of skew-feed rollers, a third pair of skew-feed rollers, as skewing at the downstream side of the second pair of skew-feed rollers, and a reference member that is arranged along a sheet conveying direction and that corrects the skew feeding of the sheet in such a manner that a side end of the sheet, which is conveyed as being skewed by the respective pairs of skew-feed rollers, is brought into contact with the reference member, wherein the first pair of skew-feed rollers releases the nip of the sheet by separating the rollers from each other before the sheet is nipped by the third pair of skew-feed rollers after the sheet is nipped by the second pair of skew-feed rollers. | 04-19-2012 |
20130113158 | IMAGE FORMING APPARATUS - A reference member which regulates a position of one side end of a sheet along the sheet conveying direction is provided at one side of a sheet conveying path in the width direction so as to follow the sheet conveying direction and to be rotatable about its downstream end portion in the sheet conveying direction. Then, one side end of the sheet is skew-conveyed toward the reference member by a plurality of pair of skew-conveying rollers which is arranged in the sheet conveying path along the sheet conveying direction. Then, when forming an image on both faces of the sheet, a control portion rotates the reference member so that the sheet is displaced to the center side in the sheet conveying path compared to the case of forming an image on one face of the sheet. | 05-09-2013 |
