Abstract
PURPOSE:To provide a cleaning blade with self-lubrication and to perform excellent copying without adding a lubricating oil to toner, by forming the cleaning blade by adding silicone oil containing a group reactive on organic materials before rubber cross-links to urethane rubber having a specific hardness range. CONSTITUTION:The cleaning blade 9 of the photoreceptor 1 of an electronic copying machine is formed by adding 0.1-10% silicone oil (e.g. modified silicone oil of SH8427, tec., or silicone oil having NH2, a glycidyl group, etc.) having a group reactive on organic materials to an urethane rubber material having 60-80 Shore A hardness before the cross-linking process of the urethane rubber. Consequently, the cleaning blade 9 itself has a lubricating function and the need to giving lubricity between the photoreceptor 1 and blade 9 by adding lubricating oil to toner 10 is eliminated, thereby obtaining excellent copies all the time.
