3 . Transfer block
This block is used to transfer the toner image on the surface of the photosensitive drum to paper.
Step 4: transfer
Positive charges are applied to the back of paper to draw toner to the face of the paper from the
photosensitive drum. A roller transfer method is used, which allows smooth movement of paper
and reduction of generated ozone.
Step 5: separation
The rigidity of paper is used to separate paper from the photosensitive drum.
The static eliminating brush is used to prevent the toner image from flying astray in dots when
paper is separated (by separation static charges); i.e., the static eliminating brush attenuates the
charges on the back of the paper.
