Image forming apparatus, control method of image forming apparatus, bookbinding apparatus and control method of bookbinding apparatus

An image forming apparatus connected to a bookbinding apparatus including a stack tray on which a plurality of sheets to be bookbound are stacked and configured to performs a cutting process of cutting a binding member for binding the plurality of sheets in accordance with a size of the sheets before the plurality of sheets are stacked on the stack tray and perform a binding process of binding stacked sheets by the binding member which is cut, the image forming apparatus comprising:

• a printing unit configured to print on the sheets based on print job;
• and
• a controller configured to transmit size information indicating a size of the sheets to the bookbinding apparatus, the controller instructing, in a case where the controller controls to produce a plurality of copies of bookbound products on each of which the binding process is performed, the bookbinding apparatus not to perform the cutting process of the binding member to be used in the binding process of a second copy while sheets are stacking as a first copy, but to perform the cutting process of the binding member to be used in the binding process of a next copy while sheets are stacking as each of the second copy and subsequent copies.

A control method of an image forming apparatus including a printing unit configured to print on a sheet based on print job, a bookbinding unit having a stack tray on which a plurality of sheets on which printing is performed by the printing unit are stacked and configured to perform a cutting process of cutting a binding member for binding the plurality of sheets in accordance with a size of the sheets before the plurality of sheets are stacked on the stack tray and perform a binding process of binding stacked sheets by the binding member which is cut, and a controller configured to cause the bookbinding unit to perform the cutting process of the binding member based on sheet size information included in the print job, the control method comprising:

• controlling, in a case where the controller controls to produce a plurality of copies of bookbound products on each of which the binding process is performed, not to perform the cutting process of the binding member to be used in the binding process of a second copy while sheets are stacking as a first copy, but to perform the cutting process of the binding member to be used in the binding process of a next copy while sheets are stacking as each of the second copy and subsequent copies.
