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 page comes in contact with the photosensitive drum, the toner is transferred to the paper. Figure 1-20 Transfer Photosensitive drum Media Transfer roller 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. Figure 1-21 Separation Photosensitive drum Media Static charge eliminator Transfer roller Fusing stage Step 6 :
The DC negative bias applied to the fusing film strengthens the holding force of the toner on the paper and prevents the toner from scattering. ENWW Image-formation system 29
