2. Operational explanation
4. Transfer
Th
e transfer roller, which is from conductive sponge material, is created to meet intimate attachment
of image drum roller surface and feeding paper. The feeding paper is set up on the surface of image
drum. Plus charge, which is the converse polarity with toner polarity, is applied from the backside of the
paper.
As high plus voltage is applied to transfer roller from the power supply, the plus charge on the transfer
roller surface is induced and transferred to the paper while the paper contact the transfer roller. The
negative charged toner, which has been attracted to the image drum surface, is transferred to the
surface of feeding paper by the plus charge of the backside of the paper.
