Transfer stage Step 4: The transfer charging roller, to which a DC positive bias is applied, imparts a positive charge on the paper. When the paper comes in contact with the photosensitive drum, the toner is transferred to the paper. Figure 1-19 Transfer Photosensitive drum Transfer roller Media DC bias Step 5: The elasticity of the paper causes its separation from the photosensitive drum. A static charge eliminator aids separation by weakening any electrostatic adhesion.
