摘要： Conveyor rollers 1a, 1b which are driven by a rotary drive motor 9 are disposed in different locations in a direction in which a sheet is conveyed. The conveyor rollers 1a, 1b are arranged so as to be able to move in a direction intersecting the direction of conveyance by means of sheet shift means which are driven by shift motors 11a, 11b. Sheet sensors 13a, 13b are provided in the reference position for the side edge of the sheet. If the sheet sensor 13a (or 13b) does not detect the side edge of the sheet 2, the shift motors 11a, 11b are controlled in such a way that a conveyor roller 1a (or 1b) corresponding to the sheet sensor approaches the sheet side edge reference position. In contrast, if the sheet sensor detects the side edge of the sheet 2, the shift motors are controlled in such a way that the conveyor roller departs from the reference position.

摘要： An image forming apparatus includes a sheet feeding unit, a manual sheet feeding unit, an image forming unit, first and second sheet conveyance paths, and an air-blowing unit. The first sheet conveyance path conveys the recording sheet from the sheet feeding unit to the image forming unit. The second sheet conveyance path conveys the recording sheet from the manual sheet feeding unit to the image forming unit. The air-blowing unit blows air to an edge of the recording sheets stacked on the manual sheet feeding unit. The first and second sheet conveyance paths are merged together before the first and second sheet conveyance paths reach the image forming unit. The air-blowing unit is disposed in a space defined between the first and second sheet conveyance paths before merged and in a vicinity of the first and second sheet conveyance paths.

摘要： A digital copier is designed to minimize image imperfections by limiting pickup of contaminants by an image carrier. Paper sheets are conveyed to an image transfer area by use of a conveyor unit. The conveyor unit includes paper feed rollers. The image transfer area includes the image carrier and a transfer roller. The paper sheets pass between the image carrier and the transfer roller. When no paper sheets are in the image transfer area, the transfer roller is in contact with the image carrier. The transfer rollers and the paper feed rollers include a rubber material with a solubility parameter chosen to minimize transfer of contaminants to the image carrier. In one example, the transfer roller and the paper feed roller are formed from a rubber material having a solubility parameter greater than or equal to 8.2 (cal/cm.sup.3).sup.1/2. To further minimize imperfections in the image due to pickup of contaminants, the rubber material of the paper feed member has a dielectric constant greater than or equal to 4.5 and has a substituent other than hydrocarbon radicals attached to the principal polymer chain. Finally, the peripheral speed of the image carrier is designed to equal the speed of the paper sheet, while the speed of the transfer roller exceeds the speed of the paper sheet. As a result, contaminants are transferred to the transfer roller and not to the image carrier.
