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.

2. The recording material processing apparatus according to claim 1 , wherein the image forming apparatus further includes:

an apparatus housing that houses the imaging section therein;

a protruding portion that is provided upward at one top portion of the apparatus housing; and

an image reading device that reads a document image, wherein the image reading device installed above the protruding portion, and

the image reading device and the top portion of the apparatus housing except the protruding portion forms a space therebetween, and

the post-processing device further includes:

a post-processing device housing that houses the post-processing section therein, and has a lateral-direction housing portion which is arranged in the space,

the lateral-direction housing portion extends in a lateral direction and in a state where the upper area of the space is left, and

a top portion of the lateral-direction housing portion is used as the first recording material output portion.

3. The recording material processing apparatus according to claim 1 , wherein

the post-processing device includes the curved transport path near an entrance of the transport path in the post-processing device housing; and

the post-processing section is a punching section having a puncher which comes into contact with or separates from the curved transport path.

4. The recording material processing apparatus according to claim 3 , wherein

the post-processing device includes a punch controlling section that controls a punching operation by the punching section; and

the punch controlling section controls the punching section so that a punching position on the recording material is determined based on the distance from a lead edge portion of the recording material transported in the transport path and the punching operation is performed.

5. The recording material processing apparatus according to claim 1 , wherein

a plurality of transport members is provided on the transport path of the post-processing device,

the plurality of transport members gives transporting powers to the recording material, and

the plural transport members are arranged at intervals in which only the recording material having the post-processing permissible size and thickness can be transported.

6. The recording material processing apparatus according to claim 1 , further comprising:

a post-processing selection section that determines whether the post-processing on the recording material used in the image forming apparatus is performed or not, wherein the recording material transport controlling section permits, when the recording material judging section judges the recording material has the post-processing permissible size and thickness and the post-processing selection section determines that the post processing is performed, 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 and the post-processing selection section determines that the post-processing is not performed, the recording material to be transported to the first recording material output portion.

7. 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 thickness to a post-processing;

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 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 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 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 thickness cannot follow, wherein

the post-processing section is provided correspondingly to the curved transport path.
