Latest Patents

Suematsu holds a patent for a conductive roller transfer device designed to improve toner image transferring processes. This device features a roller made from a conductive rubber foam material with a resistivity of more than 10⁷ Ω.cm. In the toner image transferring process, a constant current is applied to the roller, allowing for the effective transfer of a charged toner image to paper at a desired efficiency. This technology is particularly advantageous as it maintains transfer efficiency regardless of the size of the paper. Additionally, to mitigate toner pollution on the roller, a constant voltage with an opposite polarity to that of the charged toner is applied. The roller is designed with pore openings on its surface, ensuring that any residual toner does not leave stains on the paper.
