         2 . An image forming apparatus comprising:
 a non-sheet stacker which is adjacent to a downstream side in a sheet conveyance direction of an image forming apparatus main body and applies post-processing to a sheet output from the image forming apparatus main body; and   a plurality of sheet stackers located on a downstream side in the sheet conveyance direction of the non-sheet stacker, wherein   a discharger is disposed adjacent to an upstream side in the sheet conveyance direction of each of the plurality of sheet stackers.   
     
     
         3 . The image forming apparatus according to  claim 1 , wherein a discharger is insertable between the non-sheet stackers, between the non-sheet stacker and the sheet stacker, or between the sheet stackers. 
     
     
         4 . The image forming apparatus according to  claim 3 , wherein the discharger includes a connecting member which is connected to a connector provided in the non-sheet stacker or the sheet stacker located on both sides of the discharger by inserting the discharger from a front surface. 
     
     
         5 . The image forming apparatus according to  claim 1 , wherein an insulator cover is provided around the discharger. 
     
     
         6 . The image forming apparatus according to  claim 1 , wherein an insulator guide plate is provided on a lower side of a sheet path through which the sheet passes in the discharger. 
     
     
         7 . The image forming apparatus according to  claim 1 , wherein in a case where the non-sheet stacker is a post-processing device including a stacker for the sheet, a discharger is disposed adjacent to an upstream side in the sheet conveyance direction of the non-sheet stacker. 
     
     
         8 . The image forming apparatus according to  claim 1 , wherein the discharger is disposed on each of an upper side and a lower side of a sheet path through which the sheet passes. 
     
     
         9 . The image forming apparatus according to  claim 1 , wherein the discharger is of a non-contact ion type. 
     
     
         10 . The image forming apparatus according to  claim 9 , wherein a voltage application method of the discharger is an AC method. 
     
     
         11 . The image forming apparatus according to  claim 9 , wherein a voltage application method of the discharger is any of a DC method, a pulse AC method, a pulse DC method, and a high-frequency AC method. 
     
     
         12 . The image forming apparatus according to  claim 2 , wherein a discharger is insertable between the non-sheet stackers, between the non-sheet stacker and the sheet stacker, or between the sheet stackers. 
     
     
         13 . The image forming apparatus according to  claim 12 , wherein the discharger includes a connecting member which is connected to a connector provided in the non-sheet stacker or the sheet stacker located on both sides of the discharger by inserting the discharger from a front surface. 
     
     
         14 . The image forming apparatus according to  claim 2 , wherein an insulator cover is provided around the discharger. 
     
     
         15 . The image forming apparatus according to  claim 2 , wherein an insulator guide plate is provided on a lower side of a sheet path through which the sheet passes in the discharger. 
     
     
         16 . The image forming apparatus according to  claim 2 , wherein in a case where the non-sheet stacker is a post-processing device including a stacker for the sheet, a discharger is disposed adjacent to an upstream side in the sheet conveyance direction of the non-sheet stacker. 
     
     
         17 . The image forming apparatus according to  claim 2 , wherein the discharger is disposed on each of an upper side and a lower side of a sheet path through which the sheet passes. 
     
     
         18 . The image forming apparatus according to  claim 2 , wherein the discharger is of a non-contact ion type. 
     
     
         19 . The image forming apparatus according to  claim 18 , wherein a voltage application method of the discharger is an AC method. 
     
     
         20 . The image forming apparatus according to  claim 18 , wherein a voltage application method of the discharger is any of a DC method, a pulse AC method, a pulse DC method, and a high-frequency AC method.
