Title: Innovations of Hideki Kamaji
Introduction
Hideki Kamaji is a prominent inventor based in Kawasaki, Japan. He has made significant contributions to the field of electrophotographic recording technology. With a total of 11 patents to his name, Kamaji continues to push the boundaries of innovation in his industry.
Latest Patents
One of his latest patents is a recording apparatus responsive to changing electrical resistance of transfer media. This innovative image transferring apparatus holds a print sheet in a nip between an image carrier and a transfer roller. It supplies current to the transfer roller to transfer a toner image formed on the image carrier to the print medium. The apparatus features conductive brushes that are disposed in contact with the ends of the transfer roller to form a bypass circuit. This bypass circuit is connected to ground through a resistor, introducing part of the current supplied to the transfer roller during the image transferring operation. This design helps avoid print defects such as discharge-caused marks or toner stops.
Another notable patent is an electrophotographic recording apparatus using a developing device with a one-component type developer. This apparatus includes a photosensitive drum on which an electrostatic latent image can be written. It features a developing device for developing the latent image of a charged visible image with a one-component developer. The developing device has a conductive foam rubber roller that entrains the developer to form a developer layer around it. This roller brings the layer to the drum for the development of the latent image. Additionally, it includes a conductive blade that is resiliently engaged with the foam rubber roller to uniformly regulate the thickness of the developer. An electric source applies energy to the blade to electrically charge the developer layer by a charge-injection effect.
