6.5 1st transfer process (Step 4)
Toner on each drum of Y, M, C and K is transferred onto the transfer belt, this allows for overlapping of the
colors. This movement of toner from the drum to the transfer belt is referred to as the 1st transfer, where
the transfer of toner is carried out sequentially in the order of Y, M, C and K.
While in the 1st transfer, the 1st transfer roller provided at the rear of the transfer belt is applied with a high
DC bias voltage (positive). As a result, a positive potential on the surface of the transfer belt is higher than
that of the surface of each drum, and toner moves from the drum to the transfer belt.
