2-1-5 Transfer/Separation section
The transfer/separation section consists of the intermediate transfer unit section and the secondary transfer
roller section.
(1) Intermediate transfer unit section
The intermediate transfer unit section consists of the transfer cleaning unit, the transfer belt, and the four pri-
mary transfer rollers for respective color drums, and forms a full-color toner image by superimposing and
transferring single-color toner images formed on each drum onto the transfer belt. Also with the ID sensors
(IDS) mounted on the machine frame, the toner density on the transfer belt is measured.
The transfer cleaning unit collects toner remaining on the transfer belt after secondary transfer and forwards it
as waste toner to the waste toner box.
