R76-
(5) Transfer
The transfer roller is composed of conductive sponge material, and is designed to get the
image drum surface and the paper in a close contact.
Paper is placed over the image drum surface, and the positive charge, opposite in polarity
to that of the toner, is applied to the paper from the reverse side.
The application of a high positive voltage the from the power supply to the transfer roller
causes the positive charge inducement on the transfer roller surface, transferring the
charge to the paper as it contacts the transfer roller. The toner with negative charge is
attracted to the image drum surface, and it is transferred to the upper side of the paper
due to the positive charge on the reverse side of the paper.
