ABSTRACT:
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.
