         10 . An image forming apparatus comprising:
 an execution unit configured to execute printing of a plurality of copies based on an original image by causing a feeding stage set for each of the plurality copies to perform feeding; and   a control unit configured to control a feed operation so as to perform feeding from the feeding stage upon scaling the original image in a case where a sheet attribute designated in a job for executing the printing of the plurality of copies by the execution unit and a sheet attribute set in a feeding stage which serves as a feed target are different from each other.   
     
     
         11 . The apparatus according to  claim 10 , wherein the sheet attribute is a size, and
 in a case where a size designated in the job is larger than a size designated in the feeding stage which serves as the feed target, the control unit performs feeding from the feeding stage upon reducing the size of the original image.   
     
     
         12 . The apparatus according to  claim 10 , wherein in a case where a size designated in the job is smaller than a size designated in the feeding stage which serves as the feed target, the control unit performs feeding from the feeding stage upon enlarging the size of the original image. 
     
     
         13 . The apparatus according to  claim 10 , further comprising:
 a first scaling setting unit configured to set whether to perform scaling on the original image by the control unit.   
     
     
         14 . The apparatus according to  claim 13 , further comprising:
 a second scaling setting unit configured to set whether to permit respective of enlargement and reduction of the original image in a case where the setting to perform scaling on the original image has been made by the first scaling setting unit.   
     
     
         15 . The apparatus according to  claim 14 , wherein the first scaling setting unit and the second scaling setting unit perform setting based on a setting from a user interface screen.
