Image forming apparatus for designating sheet post-processing functions

An image forming apparatus, comprising:

• an image forming device which forms an image on a sheet;
• a stapling device which applies staple processing to a portion assuming a trailing end of the sheet with respect to a transport direction of the sheet;
• a punch device which selectively applies punch processing between a portion assuming a leading end of the sheet with respect to the transport direction of the sheet and a portion assuming a trailing end of the sheet with respect to the transport direction of the sheet;
• a mode setting device which sets a post-processing mode including a staple mode for applying staple processing to a portion assuming a trailing end of a sheet with respect to the transport direction of the sheet by the stapling device, a first punch mode for applying punch processing to the portion assuming a leading end of the sheet with respect to the transport direction of the sheet by the punch device, and a second punch mode for applying punch processing to the portion assuming a trailing end of the sheet with respect to the transport direction of the sheet by the punch device;
• and
• a controller which controls the mode setting device to inhibit a setting of the staple mode when the first punch mode is set, and to inhibit a setting of the first punch mode when the staple mode is set, and to allow a setting of the second punch mode when the staple mode is set.

A control method for controlling an image forming apparatus that includes:

• a stapling device which applies staple processing to a portion assuming a trailing end of a sheet with respect to a transport direction of the sheet;
• a first punch device which applies punch processing to a portion assuming a leading end of the sheet with respect to the transport direction of the sheet;
• and a second punch device which applies the punch processing to the portion assuming the trailing end of the sheet with respect to the transport direction of the sheet, the control method comprising:
• a determination step of determining a setting of a post-processing mode including a staple mode for performing the staple processing by the stapling device, a first punch mode for performing the punch processing by the first punch device, and a second punch mode for performing the punch processing by the second punch device;
• and
• a mode setting step of inhibiting a setting of both the staple mode by the stapling device and the first punch mode by the first punch device, and allowing a setting of both the staple mode by the stapling device and the second punch mode by the second punch device.
