  According to the process of FIG. 11, the paper feed tray storing the recording paper of the gap information 509 in the same direction as the direction of the crease C given in the folding process is selected. The crease C can be made on the recording paper in the same direction as the above direction, so that the quality of the crease attached to the recording paper can be improved.

  When a plurality of paper feed trays are selected in step S1109, or in step S1108, a paper feed tray storing the recording paper of the gap information 509 in the same direction as the direction of the crease C to be given is stored. Is selected, the paper feed tray with the shortest transport distance from the selected paper feed trays to the secondary transfer unit 113 may be selected. In this case, the recording paper passes through the secondary transfer unit 113. It is possible to reduce the time required until the paper is discharged to the paper discharge trays 213 and 214, and the folds can be efficiently formed on the recording paper.

  Further, when a plurality of paper feed trays are selected in step 1109, or in step S1108, a paper feed tray storing the recording paper of the gap information 509 in the same direction as the direction of the crease C to be given is stored. Is selected, a paper feed tray having a small paper feed tray number 401 (identification number) in the paper feed tray management table 400 may be selected. In this case, for example, frequently used recording paper is fed into the paper feed tray. By storing in a small paper feed tray number 401, the user can easily manage the consumption of recording paper.

  Next, a paper feed tray selection process as a modification of the control method of the image forming apparatus according to the embodiment of the present invention will be described.

  FIG. 12 is a flowchart showing the procedure of a modified example of the paper feed tray selection process of FIG.

  Steps S1101 to S1110 in FIG. 12 are the same as the processes in steps S1101 to S1110 in FIG. 11, and only differences from the processing in FIG. 11 will be described below.

  In FIG. 12, when the folding process is executed as a result of the determination in step S1106, it is further determined whether or not the crease process is executed (step S1201). When the crease process is executed as a result of the determination in step S1201, the process proceeds to step S1109. When the crease process is not executed, for example, when a record sheet having the record sheet information that matches the record sheet information acquired in step S1102 is stored, step S1103 is performed. If the type of recording paper stored in the paper feed tray determined in step S is film, the process advances to step S1108.

  According to the process of FIG. 12, when executing the crease process, the process does not proceed to step S1108 but proceeds to step S1109. Therefore, when selecting the paper feed tray to be used, the recording stored in each paper feed tray is performed. It is not necessary to consider the paper gap information 509, and the paper feed tray to be used can be easily selected.

  Software (program) for realizing the functions of the above-described embodiments is supplied to a system or apparatus via a network or various storage media, and a computer (or CPU, MPU, etc.) of the system or apparatus reads out and executes the program. In the processing, the program and a computer-readable storage medium storing the program constitute the present invention.
