Sleeve Roller

• The Sleeve Roller consists of a Developing Sleeve and Flexible Sleeve.
• The Flexible Sleeve has a diameter greater than the Developing Sleeve does. The Sleeve
Guide presses the Flexible Sleeve against the Developing Sleeve to form a slack in it.
• The slack in the Flexible Sleeve is brought into contact with the surface of the PC Drum to
let an even amount of toner stick to the PC Drum.
