3.4.5 Fixing Process
The image which has been transferred to the recording paper in the transfer process only ad-
heres to the recording paper by the force of the charge (static electricity). The image would be
corrupted if touched by your hand. Therefore, the toner needs to be fused on the recording
paper to form a permanent image by the application of heat and pressure to both the toner and
recording paper.
A fluorine resin coating which has superior anti-adhesive properties is applied to the Heat roller
surface. To prevent winding or creasing of the recording paper, the Fuser cleaner contains
silicon oil. The oil is applied to the Heat roller in small quantities each time the roller turns.
