| 1. A sheet post-processing apparatus comprising:
a standby tray that subjects a sheet discharged from an image forming apparatus to buffering while the sheet is sent to a
conveying path at a next stage;
a processing tray that is arranged below the standby tray and on which the sheet dropped and supplied from the standby tray
and/or the sheet discharged from the image forming apparatus without passing through the standby tray is stacked;
driving rollers that are arranged in a leading end position in a sheet conveying direction of the standby tray and rotating
shafts of which are perpendicular to the sheet conveying direction; and
driven rollers that rotate following the driving rollers and are provided on left and right with respect to the sheet conveying
direction, rotating shafts of which are not parallel to the rotating shafts of the driving rollers and an intersection of
the rotating shafts of which is located further on a downstream side in the sheet conveying direction than the rotating shafts
of the driving rollers, the driven rollers being attached to a front portion in the sheet conveying direction of the standby
tray, the driven rollers being attached to both end portions in horizontal direction of the sheet in the sheet conveying direction
of the standby tray.
