• In order to remove the remaining toner on the 2nd image transfer roller, -/+ (DC) charge
is applied alternately to transfer the remaining toner on the 2nd image transfer roller to
the transfer belt.
(The number of times that electrical charge is applied to the 2nd image transfer roller is
different depending on each situation.)
• The cleaning blade then scrapes off the toner on the surface of the transfer belt.
