Latest Patents

Fujimoto's latest patents include a sophisticated fixing device that features a heating rotor, a pressure belt, a sheet member, first and second pressurizing members, a motor, and a control unit. The control unit is designed to manage the motor's rotation of the heating rotor and pressure belt in a direction opposite to the conveyance direction of the recording material during startup after a jam treatment. This innovative design allows for the adjustment of contact positions of the sheet member with respect to the pressurizing members, ensuring that the sheet member does not obstruct their independent actions. This results in maintaining the proper nip width and pressure, enhancing the stability of the fixing device and improving the fixability and conveyability of the recording material.

Another significant patent involves a fixing apparatus that secures a fixing nip through a pressure belt and a fixing roller. This belt-nip system reduces the frequency of replacing the pressure belt or sliding sheet. The fixing apparatus is capable of switching pressure distribution in the roller axis direction based on sheet measurement, ensuring that the necessary pressure for fixing is maintained throughout the apparatus.
