Method for producing a metallic core for use in cylinder sleeves for an electrophotographic process

Abstract

An improved method for producing a metallic core for use in the production of a blanket cylinder or an image cylinder sleeve for use in electophotographic processes. The sleeves includes aluminum or other suitable metal, which is rendered more suitable for use as a sleeve surface by oxidation.

1 . An image cylinder for an electrophotograpic process comprising: 
 a) a metallic core having at least one of its inner and its outer surfaces oxidized; and    b) at least one layer of a photosensitive image-accepting layer around the outside of the outer surface of the metallic core.    
   
   
       2 . The image cylinder of  claim 1 , wherein the image cylinder includes a plurality of layers around the outside of the metallic core.  
   
   
       3 . An image cylinder for an electrophotograpic process comprising: 
 a) an aluminum core having at least one of its inner and its outer surfaces oxidized; and    b) at least one layer of a photosensitive image-accepting layer around the outside of the outer surface of the aluminum core.    
   
   
       4 . The image cylinder of  claim 3 , wherein the image cylinder includes a plurality of layers around the outside of the aluminum core.  
   
   
       5 . A blanket cylinder for an electrophotographic process comprising: 
 a) an aluminum core having at least one of its inner and outer surfaces oxidized; and    b) at least one layer of an image-transferring material around the outside of the outer surface of the aluminum core.
