9. The recording material processing apparatus according to claim 1 ,

wherein when a new recording material set comprising one or more recording materials is loaded on a loading position on an already loaded recording material set already loaded on the recording material support portion, the new recording material set newly loaded on the loading position of the already loaded recording material set becomes an other already loaded recording material set, and then another new recording material set is further loaded on a loading position of the other already loaded recording material set, and

wherein the loading position is sequentially shifted in one direction when each new recording material set is loaded.

10. An image forming system comprising:

an image forming apparatus configured to form an image on a recording material; and

a recording material processing apparatus configured to process a recording material,

wherein the recording material processing apparatus includes the recording material processing apparatus according to claim 1 .

11. An image forming system comprising:

an image forming apparatus configured to form an image on a recording material; and

a recording material processing apparatus configured to process a recording material,

wherein the recording material processing apparatus comprises:

a support portion configured to support, from below, a recording material discharged to the support portion after being transported from the image forming apparatus; and

a contact member including a contact surface that advances to a recording material from a side of the recording material supported by the support portion and is in contact with an edge portion of the recording material,

wherein the contact member is vertically movable with respect to the support portion, and

wherein the contact surface faces obliquely downward when the contact surface is in contact with the edge portion and pushes the edge portion.

12. The recording material processing apparatus according to claim 11 , further comprising:

an advancing portion configured to advance to the recording material together with the contact member, the advancing portion being provided on a side opposite to a side of the recording material with respect to the contact member, and

an elastic member provided between the contact member and the advancing portion.

13. The recording material processing apparatus according to claim 12 ,

wherein the elastic member is a coil spring, and

wherein the contact member has a portion positioned below a central axis of the coil spring, the portion being configured to contact with the edge portion of a recording material.

14. The recording material processing apparatus according to claim 11 , further comprising:

an advancing portion configured to advance to the recording material together with the contact member, the advancing portion being provided on a side opposite to a side of the recording material with respect to the contact member,

wherein the contact member is supported by the advancing portion,

wherein the contact member is disposed in a state of being inclined with respect to a vertical direction when the contact surface is in contact with the edge portion and pushes the edge portion, and

wherein the advancing portion is disposed in a state of being along a vertical direction when the contact surface is in contact with the edge portion and pushes the edge portion.

15. The recording material processing apparatus according to claim 11 , further comprising:

an advancing portion configured to advance to the recording material together with the contact member, the advancing portion being provided on a side opposite to a side of the recording material with respect to the contact member,

wherein the contact member is supported by the advancing portion,

wherein the contact member changes a posture when the contact member is advanced toward the recording material and is in contact with the edge portion, and the contact surface faces obliquely downward with the change of the posture, and
