Description
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 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
temporarily by static electricity on
the Image drum surface.
