This block consists of four steps and the toner image on the photosensitive drum surface is transferred onto paper.
Step 5: Attraction
Paper is adhered on the ETB by electrostatic force in this step.
It is necessary to adhere paper on the ETB in order to convey the paper upward. The picked up paper is fed as it is pushed against the ETB by the attraction roller.
The positive DC bias is applied to the attraction roller to charge the paper positive.

Step 6: Transfer
A toner image on the photosensitive drum is transferred onto paper in this step.
The positive DC bias is applied to the transfer roller facing to the photosensitive drum to charge the ETB positive. Then the negative charged toner on the drum
surface is transferred onto the paper. This process is repeated for each color (M, C, Y and Bk).
