ABSTRACT:
A sheet bending apparatus and a sheet postprocessing apparatus are provided for improving an alignment of recording sheets at the time of center-folding processing. A controller of the center-folding unit mounted in the sheet postprocessing apparatus performs: a first processing of making the upper side end aligning members approach a recording sheet in course of being conveyed into the sheet holding member a predetermined distance shorter than a predetermined approaching distance; a second processing of making the upper side end aligning members approach the recording sheet placed in the sheet holding member a remainder of the approaching distance; and a third processing of making the lower side end aligning members approach the recording sheet placed in the sheet holding member a predetermined approaching distance within a period when the second processing is performed.
