    摘要： A sheet processing apparatus (2) includes: a folding unit (215, 230) that folds a sheet bundle (SB); a pressing unit (260) that presses a fold part of the sheet bundle (SB), which has been folded by the folding unit (215, 230), in a thickness direction of the sheet bundle (SB) to enhance folding of the fold part; and a moving unit (263) that advances and returns the pressing unit (260) in a width direction of the sheet bundle (SB). The pressing unit (260) starts pressing from a predetermined position in the width direction of the sheet bundle (SB) during advancing movement, and releases pressing after going past one end of the sheet bundle (SB). The pressing unit (260) starts pressing from the predetermined position during return movement and goes past the other end of the sheet bundle (SB).

    摘要： A spine formation device (3) includes a sheet conveyer (31) to convey a bundle of folded sheets with a folded portion of the bundle forming a front end of the bundle, a clamping unit (32,325,326) disposed downstream from the sheet conveyer (31) in a sheet conveyance direction for squeezing a folded portion of the bundle in a direction of thickness of the bundle, a contact member (330) against which the folded portion of the bundle is pressed, disposed downstream from the clamping unit (32,325,326), an elevation unit (331,332) to move the contact member (330) vertically, and a controller (3-1). The clamping unit (32,325,326) includes multiple pressure rollers (325b) arranged in a single line along the folded portion of the bundle, a planar clamping member (326) disposed facing the multiple pressure rollers (325b) vertically, to press the bundle against the multiple pressure rollers (325b), and a unit to (325s) move the pressure rollers (325b) and the clamping member close and away from each other.

    摘要： There is a need to provide a sheet post-processing apparatus capable of neatly squaring a booklet spine without any damage such as a wrinkle on the spine and an image forming apparatus having the sheet post-processing apparatus.
    According to the sheet post-processing apparatus, a drive motor(SM9) drives first and second pressing members(650,651). A circumferential velocity(V1,V2) of the pressing member(650,651) on a pressing surface pressed against the booklet(2a) spine(2a1) is configured to be reverse to a moving velocity(W) of a moving portion(656a), and to be greater than the moving velocity (W).

    摘要： A sheet processing apparatus (1000) that can process a folded sheet bundle, comprising: deforming processing means (640) configured to perform deforming processing by deforming a folded spinal portion of the folded sheet bundle to form a substantially flat portion along the folded spinal portion; and cutting means (621, 622) configured to cut an edge portion, opposite to the folded spinal portion, of the folded sheet bundle, wherein the distance from the folded spinal portion of a folded sheet bundle to a position to be cut by the cutting means (621, 622) is shorter for a folded sheet bundle A having a particular thickness and having been subjected to the deforming processing than the distance from the folded spinal portion of the folded sheet bundle to a position to be cut by the cutting means(621, 622) for a folded sheet bundle B not subjected to the deforming processing but having the same thickness as folded sheet bundle A.
