%(6) Transfer
(6) Transfer
The transfer roller is composed of conductive sponge material and is designed to make the image
drum surface and the paper closely into contact.
Paper is placed over the image drum surface, and a positive charge, opposite in polarity to the
toner, is applied to the paper from its reverse side.
The application of a high positive voltage from the power supply to the transfer roller causes the
positive charge induced to the transfer roller surface to be transferred to the paper at the contact
between the transfer roller and the paper. As a results, toner charged negative that is attracted to
the image drum surface is transferred to the upper side of the paper by the positive charge on the
lower side of the paper.
