Latest Patents

Lee’s listed patents address components and controls that help manage the printing process.

- **Fusing apparatus and electrophotographic image forming apparatus using the same.** This invention describes a fusing apparatus that applies heat and pressure to fix a toner image to printing media. A rotatably mounted separation member helps detach the media from a heating or pressing roller. Its design allows the member to pitch around its rotation axis and an inclined pitching axis, supporting separation at the roller surface.

- **Image forming apparatus and method for controlling fuser thereof.** This invention describes an image-forming apparatus with a heated roller, a conductive pressure roller, a power supply, and a controller. The controller applies a bias voltage to the pressure roller when paper enters the nip. Depending on the time interval between sheets, it can also control whether the voltage is applied while no paper is in the nip.

Career Highlights

Lee’s listed patent portfolio focuses on fuser mechanisms and electrical control in electrophotographic printing equipment. These inventions address media separation, roller operation, and the timing of bias voltage during printing.
