Abstract

A paper discharge tray includes a placing part on which a recording medium discharged from a paper discharge part is placed; and a projection which is provided on the placing part and includes plural apexes arranged in a paper discharge direction of the recording medium.

What is claimed is: 
     
         1 . A paper discharge tray comprising:
 a placing part on which a recording medium discharged from a paper discharge part is placed; and   a projection which is provided on the placing part and includes a plurality of apexes arranged in a paper discharge direction of the recording medium.   
     
     
         2 . The tray of  claim 1 , wherein a height of a downstream apex of the plurality of apexes in the paper discharge direction is higher than a height of an upstream apex. 
     
     
         3 . The tray of  claim 1 , wherein the placing part is inclined and a downstream side of the placing part becomes high in the paper discharge direction of the recording medium. 
     
     
         4 . An image forming apparatus comprising:
 an image forming part to form an image on a recording medium;   a paper discharge part to discharge the recording medium having the image;   a placing part on which the recording medium discharged from the paper discharge part is placed; and   a projection which is provided on the placing part and includes a plurality of apexes arranged in a paper discharge direction of the recording medium.   
     
     
         5 . The apparatus of  claim 4 , wherein the paper discharge part includes a guide part to bend the recording medium in a vertical direction to the paper discharge direction. 
     
     
         6 . The apparatus of  claim 4 , wherein a height of a downstream apex of the plurality of apexes in the paper discharge direction is higher than a height of an upstream apex. 
     
     
         7 . The apparatus of  claim 4 , wherein the placing part is inclined and a downstream side of the placing part becomes high in the paper discharge direction of the recording medium.
