First transfer process (Step 4)

The toner images created on each of the Y, M, C, and K photoconductor drums are transferred to the transfer
belt one by one in the order of Y, M, C, and K. As a result, the four toner images are overlaid and a complete
toner image is formed on the belt. This is called as "first transfer."
In order to carry out the first transfer, a positive high DC voltage bias is applied to the first transfer roller provided
on the back surface of the transfer belt. This makes the transfer belt surface have a positive potential higher than
that of the each drum surface so that the toner on the drums are attracted to the transfer belt.
