2-1-5 Transfer section

The image developed by toner on the drum is transferred onto the paper because of the electrical attraction between the
toner itself and the transfer roller. The transfer roller is negatively biased so that the positively charged toner is attracted
onto the paper while it is pinched by the drum and the transfer roller.
