To prevent paper feed failure in feeding a bundle of recording materials formed by binding the recording materials with pressure.
A binding mechanism part is provided in a post-processing device to bind a recording material bundle P by applying pressure in a thickness direction of the recording material bundle P. When a recording material P is supplied from a sheet storage part 110A of an image forming device toward an image forming part, a position for forming a pressure-binding part S is set so that the recording material bundle P bound by the binding mechanism part passes a position apart from arrangement areas of a feed roll 112 and a retard roll 113 in a direction orthogonal to a conveyance direction of the recording material P. When a sheet is supplied while the position for forming the pressure-binding part S for the recording material bundle P stored in the sheet storage part 110A or the like is located at a tip in the sheet conveyance direction, the position for forming the pressure-binding part S is set so that the pressure-binding part S is located at a rear end in the sheet conveyance direction, in the binding mechanism part.
