Latest Patents

Doubata holds a patent for an "Image forming apparatus using an endless belt." This invention involves an image forming apparatus, such as an electrophotography-based copying machine or laser printer. The design features ribs along both side ends of the inner surface of an intermediate transfer belt. Rib guides are positioned on both ends of a drive roll, allowing the ribs to contact the rib guides, which effectively guides the intermediate transfer belt. The diameter of each rib guide is slightly larger than that of the drive roll, creating a gap that reduces friction between the drive roll and the intermediate transfer belt. This innovation minimizes thrust from the ribs against the rib guides, enhancing the overall efficiency of the apparatus.
