In the fixing process, toner is fixed on the paper by heat and pressure.

Finished toner image transferred from the belt is easily broken only by touching it
with fingers. The toner image is fixed on the paper with the fuser ASSY (fixing unit).

is deposited on the paper under pressure given by the belt opposed against the
heat roll.
