    摘要: An image forming unit includes an elastic roller that rotates in contact with a recording medium to apply a force thereto, a rigid roller disposed facing the elastic roller and that contacts the recording medium, and a pressing device that applies pressing force to each end of the elastic roller or the rigid roller in an axial direction to press one of the elastic roller and the rigid roller against the other. The elastic roller includes a straight roller portion disposed in a specified region extending from a center of the elastic roller toward each end of the elastic roller in the axial direction, and taper roller portions that sandwich the straight roller portion in the axial direction. Each taper roller portion has an outside diameter decreasing from an outer end of the straight roller portion toward an outer end of the elastic roller in the axial direction.

    摘要: An ink printer for printing on a recording medium using a liquid ink includes at least one rotatable member arranged in a region of a transport path of the recording medium. The rotatable member is located so as to be capable of contacting liquid ink for forming an image on the recording medium. The rotatable member includes a radially outermost perimeter portion which serves as a recording medium contacting peripheral surface. The outermost perimeter portion has an outermost edge which is continuously contactable with the printing surface of the recording medium. The bonding force with respect to the ink on the outermost edge is less than the sum of a bonding force between the recording medium and the ink on a surface of the recording medium, and the cohesive force of the ink itself on the surface of the recording medium. As a result adherence of the ink to the contacting peripheral surface of the at least one rotatable member is prevented.

    摘要: A sheet conveying device includes a metal feed roller driven by a drive source and a plastic pinch roller pressed against the feed roller. A sheet is held between the feed roller and the pinch roller, to convey the sheet to a recording unit. An elastic ring having a high wear resistance is fitted over a part of an outer surface of the pinch roller in a width direction of the pinch roller. Accordingly, the elastic deformation of the elastic ring reduces or absorbs load (impact) that causes a rear end of the sheet to flick or spring and the improper sheet feeding, when the rear end of the sheet passes through a nip portion between the feed roller and the pinch roller. Thus, variances in the sheet feeding amounts and the poor image formation are prevented.

    摘要: A recording apparatus includes a recording head, a transport driving roller, and a transport driven roller. The recording head discharges ink onto a transported recording medium, thereby performing recording. The transport driving roller is provided on the upstream side of the recording head in the transport direction and includes driving side roller portions and depressed portions. The driving side roller portions are rotationally driven, thereby transporting the recording medium. The diameter of the depressed portions is smaller than that of the driving side roller portions. The driving side roller portions and the depressed portions are arranged in a direction perpendicular to the transport direction of the recording medium in such a manner that at least one driving side roller portion alternates with at least one depressed portion. The transport driven roller is provided opposite the transport driving roller and includes driven side roller portions and presser rollers.
