Recording material processing apparatus having image forming apparatus and post processing device

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.
