a pair of second fold-forming rolls provided at a downstream side of the pair of first fold-forming rolls in the recording material transport direction, each of which includes a plurality of rolls arranged at intervals so as to correspond to positions where the blade sections of the pressing member are arranged, the pair of second fold-forming rolls further forming the folds on the bundle of recording materials by nipping portions of the bundle of recording materials, which exist between the folds formed by the pair of first fold-forming rolls.

2. The recording material processing apparatus according to claim 1 , wherein the pair of second fold-forming rolls further has a function of outputting the bundle of recording materials to an outside of the apparatus.

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

a pair of arm members to which the pair of first fold-forming rolls is attached; and

an elastic member that connects the arm members of the pair of arm members at an upstream side in the recording material transport direction,

wherein the individual arm members of the pair of arm members rotate in directions opposite to each other around fulcrums at a downstream side to form a space for nipping a bundle of recording materials between the pair of first fold-forming rolls, and

the elastic member generates a force for nipping the bundle of recording materials via the pair of arm members.

4. The recording material processing apparatus according to claim 2 , further comprising:

a pair of arm members to which the pair of first fold-forming rolls is attached; and

an elastic member that connects the arm members of the pair of arm members at an upstream side in the recording material transport direction,

wherein the individual arm members of the pair of arm members rotate in directions opposite to each other around fulcrums at a downstream side to form a space for nipping a bundle of recording materials between the pair of first fold-forming rolls, and

the elastic member generates a force for nipping the bundle of recording materials via the pair of arm members.

5. The recording material processing apparatus according to claim 3 , further comprising:

a pair of transmitting members that transmits a force for rotating the pair of first fold-forming rolls,

wherein the pair of arm members rotate around rotation centers of the pair of transmitting members as the fulcrums.

6. The recording material processing apparatus according to claim 4 , further comprising:

a pair of transmitting members that transmits a force for rotating the pair of first fold-forming rolls,

wherein the pair of arm members rotate around rotation centers of the pair of transmitting members as the fulcrums.

7. The recording material processing apparatus according to claim 3 , wherein the individual arm members of the pair of arm members are formed such that a distance between portions thereof to which the elastic member is connected becomes larger than a distance between rotation centers of the individual first fold-forming rolls of the pair of first fold-forming rolls.

8. The recording material processing apparatus according to claim 4 , wherein the individual arm members of the pair of arm members are formed such that a distance between portions thereof to which the elastic member is connected becomes larger than a distance between rotation centers of the individual first fold-forming rolls of the pair of first fold-forming rolls.

9. The recording material processing apparatus according to claim 5 , wherein the individual arm members of the pair of arm members are formed such that a distance between portions thereof to which the elastic member is connected becomes larger than a distance between rotation centers of the individual first fold-forming rolls of the pair of first fold-forming rolls.

10. The recording material processing apparatus according to claim 6 , wherein the individual arm members of the pair of arm members are formed such that a distance between portions thereof to which the elastic member is connected becomes larger than a distance between rotation centers of the individual first fold-forming rolls of the pair of first fold-forming rolls.

11. A recording material processing system comprising:

an image forming apparatus that forms an image on a recording material; and

a recording material processing apparatus that forms a fold on a bundle of recording materials formed by stacking the recording materials on each of which the image is formed by the image forming apparatus,

wherein the recording material processing apparatus comprises:

a stacker that stacks the recording materials that are sequentially transported to form the bundle of recording materials;

a pressing member that includes blade sections arranged at intervals in a width direction of the bundle of recording materials, the blade sections pressing portions of the bundle of recording materials, where folds are to be formed, stacked on the stacker, to thereby move the portions of the bundle of recording materials, where the folds are to be formed, in a recording material transport direction;
