ABSTRACT:
A feeding device including a drive roller and a driven roller opposed to the drive roller and biased toward the drive roller, such that the drive and driven rollers cooperate to feed a sheet while holding the sheet therebetween. The driven roller includes a toothed wheel portion and a contactable portion having a diameter smaller than that of the toothed wheel portion. The drive roller includes first and second portions. A radially outer end of the second portion is more distant from an axis of the drive roller than a radially outer end of the first portion. During absence of the sheet between the drive and driven rollers, the contactable portion of the driven roller is held in contact at its circumferential surface with a circumferential surface of the second portion of the drive roller, while a radially outer end of the toothed wheel portion is not in contact with a circumferential surface of the first portion. Also disclosed is an image recording apparatus including the above-described feeding device.
