Abstract: A sheet conveying apparatus according to the present invention includes: a pair of conveying rollers 13 which nips and conveys a sheet; a reference member 31 which determines the position of a side edge of the sheet along the sheet conveyance direction; a plurality of pairs of skew feeding correcting rollers 32 which nip and convey the sheet conveyed by the pair of conveying rollers 13 and draw the side edge of the sheet to the reference member 31; and a switching unit which switches the pair of conveying rollers 13 and the pairs of skew feeding correcting rollers 32 between a state of nipping the sheet and a state of nip releasing the sheet, the switching unit releasing the nip of the sheet by the pair of conveying rollers 13 after the conveyed sheet is nipped by at least two of the pairs of skew feeding correcting rollers 32.

Abstract: A sheet conveying apparatus has a conveying rotating member, a follower rotating member which is disposed to face the conveying rotating member, a support member which passes through a hollow portion of the follower rotating member and supports the follower rotating member, a pressure portion which biases the support member toward the conveying rotating member so that the follower rotating member comes into contact with the conveying rotating member a first bearing portion which is disposed between an outer peripheral surface of the support member and an inner peripheral surface of the follower rotating member and rotatable supports the follower rotating member with respect to the support member, and a second bearing portion which movably supports the support member and has a slide friction coefficient higher than that of the bearing portion.

Abstract: The sheet conveying apparatus includes first to third pairs of skew conveying rollers conveying a sheet, a reference portion, in which the reference portion corrects a skew feeding of the sheet by abutting a side edge of the sheet conveyed by the first to third pairs of skew conveying rollers against a reference surface placed in parallel with the sheet conveying direction, and a guide groove provided on the reference portion, which guides the side edge of the sheet skew-conveyed by the first to third pairs of skew conveying rollers to the reference surface, wherein a vertical width of an opening portion of the guide groove in an upstream area of the reference portion is wider than that of the guide groove in a downstream area of the reference portion, in the sheet conveying direction.
