Patent ID: 8078093

Claim:
A recording material processing apparatus comprising: an image forming apparatus including: an imaging section that forms an image on a recording material; and a first recording material output portion onto which the recording material having the image formed thereon by the imaging section is output and accommodated; a post-processing device that is provided attached to the image forming apparatus, the post-processing device including: a post-processing section that selectively subjects a recording material having post-processing permissible size and thickness to a post-processing; and a second recording material output portion onto which the recording material passed through the post-processing section is output and accommodated; a recording material judging section that judges whether the recording material used in the image forming apparatus has the post-processing permissible size and thickness or not; and a recording material transport controlling section that permits, when the recording material judging section judges the recording material has the post-processing permissible size and thickness, the recording material to be transported into the post-processing device, and permits, when the recording material judging section judges the recording material does not have the post-processing permissible size and thickness, the recording material to be transported to the first recording material output portion; a post-processing device housing that houses the post-processing section therein; a transport path that transports the recording material, the transport path is provided in the post-processing device housing; and a curved transport path which is provided at a part of the transport path, the curved transport path is curved to such a degree that the recording material not having the post-processing permissible size and thickness cannot follow, wherein the post-processing section is provided correspondingly to the curved transport path.
