A high negative voltage (approximately –5 kV) is applied to the transfer
corona wire [A], and the corona wire generates negative ions. These
negative ions are applied to the back side of the copy paper. This negative
charge forces the paper against the drum and attracts the positively charged
toner onto the paper.
A high positive voltage (approximately +2.2 kV) is applied to the discharge
plate [B]. The negative charge on the copy paper is discharged after image
transfer by this discharge plate to ensure paper separation from the drum.
The spurs [C] prevent unfused toner on the paper from being smeared by the
bottom surface of the imaging unit.
