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 sur-
face is transferred to the upper side of the
recording 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 tempo-
rarily by static electricity on the Image
drum surface.
