SHEET CONVEYING APPARATUS AND IMAGE FORMING APPARATUS

摘要

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.

主权项

1. A sheet conveying apparatus comprising:
a first rotary portion which nips and conveys a sheet; a reference surface which is provided along a direction in which the sheet is conveyed; a plurality of second rotary portions arranged along the sheet conveyance direction, each of the portions nipping and obliquely conveying the sheet conveyed by the first rotary portion so as to contact the side edge of the sheet to the reference surface; a first switching portion which switches the first rotary portion between a state of nipping the sheet and a state of nip releasing the sheet; a second switching portion which switches and the second rotary portions between a state of nipping the sheet and a state of nip releasing the sheet; and a controller which controls the first switching unit and the second switching unit so that the nip of the sheet by the first rotary portion is released after the conveyed sheet is nipped by at least two of the second rotary portions.
