          Appeal No. 1998-0126                                                        
          Application 08/272,700                                                      


          electrophotographic image forming apparatus comprising:                     
                    a discharge member having sharp dicharge ends,                    
          wherein at least each discharge end portion including said                  
          discharge end is coated with a material having a high electric              
          resistance.                                                                 




          5.  A corona discharge device used in an                                    
          electrophotographic image forming apparatus comprising:                     
                    a discharge member having a plurality of sharp                    
          discharge ends arranged in a row, wherein a distance D (mm) of              
          a space between a discharge end and a charge receiving member               
          to be charged in said image forming apparatus or between said               
          discharge end and a path of said charge receiving member, and               
          a pitch P (mm) between said discharge ends are determined to                
          establish a relationship of 4#D/P#6.                                        
          6.  A corona discharge device used in an                                    
          electrophotographic image forming apparatus comprising:                     
                    a discharge member having sharp discharge ends,                   
          wherein at least each discharge end portion including said                  
          discharge end is made of an electrically conductive material                
          containing nickel in a range from 8% to 15% and chromium in a               
          range from 16% to 20%, and is coated with a material having a               
          high electric resistance.
