The recording paper is placed over the
Image drum surface and a positive charge,
opposite in polarity to the toner, is applied
to the reverse side of the paper from the
transfer roller. The toner is attracted by the
positive charge and is transferred to the
paper. The toner charged negative that is
attracted to the Image drum surface is
transferred to the upper side of the record-
ing paper by the positive charge on the
lower side of the paper.
The unfused toner image is fused on the
paper under heat and pressure as it passes
between the heater roller and the back-up
roller.
Residual toner on the Image drum is
attracted to the cleaning roller temporarily
by static electricity on the Image drum
surface.
