(8) Fusing process

Fusing is a process of melting the toner on the paper and fixing it firmly onto the paper. Method : The softening point of the toner (main

	component : resin) is 105 - 1200C.
	→
(Heat)	Toner is melted by the fuser belt.
	+

(Pressure) The fuser belt is pressed against the pressure roller by the springs to increase adherence of the melted toner to the paper.

→

The paper is subjected to the heat and pressure when passing through the fuser belt and the pressure roller.

(Fusing) The toner on the paper is fused to it.

Surface potential of photoconductive drum

While eliminating the (+) charge on the photoconductive drum applied during the transfer stage, the conductive blade recovers the toner left on the drum at the same time.

•Elimination of transfer charge

With this OPC photoconductive drum, (+) charge on their surface cannot be eliminated optically. Therefore, (–) voltage is applied to the conductive blade, which is pressed against the drum, to eliminate the (+) charge applied at the transfer process.
