 The drum is discharged and cleaned with rubber
 cleaning blades of old toner.
 
 Then the drum is uniformly charged.
 
 The uniform charge is then discharged in those
 areas where images are to be produced.
 
 Toner is then attracted to the discharged areas.
 
 [To extremely simplify the process.]
