Abstract:
An aspect of the invention provides a sheet conveying apparatus, an image forming apparatus, and an image reading apparatus, in which generation of skew feeding caused by the shock in pressure contact of a rotation body can be reduced. An interlocking mechanism brings a driven roller 222 biased by a biasing member into pressure contact with a feeding portion 221c of a driving roller 221 in conjunction with rotation of the driving roller 221. The driving roller 221 includes a non-feeding portion 221d in a circumferential surface thereof. The driven roller 222 is caused to abut on a pressure holder 225 before the driven roller 222 moved in a direction in which the interlocking mechanism brings the driven roller 222 into the pressure contact with the driving roller 221 is brought into the pressure contact with the driving roller 221.
