Transfer - Oki OKIOFFICE44 Service Manual

Transfer

The transfer roller is composed of conductive sponge material. This roller is set so that the surface of the
image drum and sheets of paper will adhere closely.
A sheet of paper is placed on the surface of the image drum and the positive charge opposite to the negative
charge of a toner is applied from the reverse side by the transfer roller.
When a high negative voltage is applied from the power supply to the transfer roller, the positive charge
induced on the surface of the transfer roller moves to the paper side at the contact part between the transfer
roller and the sheet of paper. The positive charge on the lower side of the sheet of paper then causes the
negatively charged toner adhering to the surface of the image drum to move to the upper side of the sheet.
This enables transfer to the sheet of paper.
